- In this video www.coolersonsale.com test which form of ice is the best? Will Dry Ice in a cooler last longer than cubed ice or frozen blocks of ice?
Lifetime 55Qt Cooler: amzn.to/2Ly8kpy
See The Results: www.coolersonsale.com/differen...
We used three IDENTICAL Lifetime 55Qt Coolers to test three variations of 15lbs of ice: Cubed, Block & Dry Ice.
What we have found is the coldest form of ice does not necessarily last the longest..... nor is it optimal for certain items.....you'll see from the explosion. We were recently contacted by a reader that suggested that we also include important information regarding dry ice and when it sublimes it becomes carbon dioxide (CO2). There have been several studies showing that enough dry ice in a sealed environment (like a car) can displace the oxygen as the dry ice sublimes. When using dry ice take extra caution with not only handling dry ice but also take extra precautions to ensure environments where stored are adequately ventilated.
It is also importable to use a dry ice compatible cooler as we did in this video. We have a full post on dry ice compatible coolers here: www.coolersonsale.com/how-to-u...

I used dry ice with regular ice back in the early 90's in a small igloo cooler while camping on the Mogollon Rim in AZ. The dry ice made the regular ice last around a week. I packed the cooler with my items. Then poured regular ice on top and around everything. Finally I wrapped the dry ice in newspaper and put that on top of the regular ice. It worked great for a week of camping without needing to go into town to buy more ice.
How many sheets of newspaper did you use? And did you tape the newspaper ends with duct tape or rubber band the newspaper?
Common bud you know that dry ice cannot be used on its own and everybody else knows it. The secret is to have a min 50Qt cooler 70-90Qt is very good and 150-250Qt is the ultimate setup for dry ice 😉
1) Dry ice on the base
2) Ice blocks on the top like yeti pelican etc
3) Then, only then you place regular ice on the top.
4) Meats
5) Dairy
6) Then cans and salads or whatever.
Result near a month of ice with opening the cooler 4 times per day with the 250Qt
#3. Why put regular ice? wont it melt and cause the dry ice to melt faster?
I was going to say pretty much the same thing. When using dry ice in a cooler, it's better to use it to keep the ice frozen longer.
Thanks for this tip, I’m going on a month long road trip and gonna use this info
dry ice needs to be seperated from the articles for best results, it usually says on the bag to seperate with newspaper or something of that nature if you dont want your stuff frozen
I would say the main convenience with dry ice is the fact that you don’t have to deal with water after the ice melts dry ice goes straight from solid to gas which is extremely good if you plan on using it for a power outage and stuffing it in your fridge. Which is what I’m gonna do with this hurricane on the way
Taking the cubed ice out of the bag is a foolish reflex, to cool the food faster (warm the ice faster). For a picnic, the coolers should be cooled first with sacrificial ice or dry ice, and then a slab of 15F ice (in a zip-lock) covering the food.
I'm always surprised how many people say "now try it this way, or that way", not seeming to realize this guy gave us this FOR FREE. Better to do your own if you want to see more things done--just saying.
They are called “suggestions” or “requests” and many RUclips channels ask for the ideas... if you, or this channel, doesn’t like them... well... don’t read them... it’s not like anyone is obligated to do them... {shrug}
I am sure he likes the feed back for future videos! don't censor us!!!!!! :)
Kick ass videos. Short, sweet and to the point. You’re getting my next cooler order.
Awesome, glad we could help!
@@CoolersOnSale yes we love you and your cooler videos :o)
This was the perfect video for my question I had.This is why I love youtube. Great vid, thanks!
Glad we could help!
On long trips, I put meat (in sealed bags) on the bottom of the cooler with blocks of ice on top. Then I set my drinks on the blocks, cover with crushed ice, and put my Veggies and cheese and such on top of that.
I would really like to see a test without opening the coolers, for packing food on long trips, and one with a mixture of dry and regular ice. The dry ice could potentially keep the water ice frozen for 2 full days, and then you'd have another day of cold, water ice.
Thanks 4 the Info👍😃
Thanks for the review. I was debating on which ice to use in our yeti to keep longer. You rock!
You should get rid of the yeti and buy a lifetime or ozark
@@Jb-qn2xz that's a dumb thing to suggest. He already spent money on a great cooler and yes there maybe better out there but the Yeti can do an excellent job for them
.
@@Jb-qn2xz Do you have personal experience with both or are you just saying this because you saw a few RUclips videos and can't afford a Yeti?
Your test are the best!!! Keep them up
If you want to make your own block ice that will last much longer, you can combine the water with some isopropyl alcohol, which will lower the freezing point of the solution, and melt much slower. A water to isopropyl ratio of 80/20, will freeze at 20F, rather than the usual freezing temp of water, 32F. A water to isopropyl ratio of 70/30, which freezes at 5F, may actually be too cold, and freeze your beverages. I have found the best combo is cubed ice, combined with quality "blue ice", Gott or Rubbermaid brand. A ten pound bag of ice, combined with three blue ices lasts for a number of days, in a Yeti 45, depending on where you store the cooler.
Thanks for the suggestion Rory. We will test this when it warms up a bit. I suspect we will see an extra day out of the new mixture. This would be consistent with our Ice Pack Test.
Efficiency for me is more important for duration of time and space, so dry ice where usable. Packing it tight is critical, and or ensuring what items you have remain in contact. I use 2 coolers, one for drinks/vegetables and the other for meats and pre-made meals. For drinks, I like to freeze your typical 16OZ and larger water bottles. I will open numerous bottles and remove about an inch or so of water, then freeze them. I also use cubes and can get many days without issue, but also be able to drink/use the water bottles I froze on the final days of the trip. I also pre freeze the ice from the store as it it typically warmer , and prime my coolers the night before by tossing prior made ice/milk jugs. For meat, the only difference is I use dry ice when I can, but also a lot of pre-made meals like spaghetti. I will take all meat out of packages like steaks, sausage, chicken, hamburgers, but also spaghetti, beans, whatever and use a vacuum sealer on everything I can. I do as much as I can at once, and ensure I do portions for each meal as so I can just toss the bags and it doesn't impact the integrity (temp) of the 2nd meal. This also allows me to boil pre-made items like spaghetti in water, as so dishes are easy to clean. When I use the vacuum sealer, I also stack them directly on top of each other as to allow the shape to freeze mold into each other. This way I have more contact, and can fit more into the cooler. For meat, I also use water bottles for cooling, but put food coloring in the water and reuse them as well. Food coloring helps me identify I do not want to drink the water per potential contamination. BTW, for these bottles, I just use old bottles I have already used adding tap water... In the end, water bottles are efficient because they fit very well and you can pack more. Big blocks of store bought ice are nice, but a waste of space since you cannot use them outside of cooling.
Not to throw a wrench into the gears here, but lowering the freezing temperature of ice is counter-intuitive to what you desire for this. If I have two coolers, 1 with solution A) regular water freezing at 32* and solution b) freezing at 20* then theoretically I'm going to have ice longer in cooler 1 with solution A. When both coolers hit internal temperatures of 20* solution B will hit a phase shift and begin transition back to the water/isopropyl in liquid form while solution A will remain in the solid phase. Only when the internal temperatures hit 32* will solution A begin the same phase shift back into liquid form. This is why in the winter you put salt on roads. It lowers the solutions freezing point to a colder temperature. Meaning, the roads stay wet longer at colder temperatures versus turning to ice sooner.
I like freezing jugs and using them for ice becuase when they melt i have good water to drink in the jugs. Not sure the alcohol would help me . but thats a cool science lesson there
@kerryphillips1 The value is in the average number of Calories the coolant can absorb from the food. I don't know if the mix helps, no matter what temp the melt is. It is still just absorbing heat at its own average 'specific heat', of Calories/F.
No one seems to speak of ice temp before it goes in. For example my chest freezer is 0 degrees and the ice machine at the grocery store is about 25. That would make a big difference.
Well the actual ice itself can never go below 32 degrees so Im not sure if it really matters.
@@JohnHarvey
That statement is 100% not correct. The temperature of a solution of water and ice will not change until it changes states and becomes ice, but at that point the temperature will drop, period. Ice in a 0 degree freezer will be 0 degrees.
For every degree F that the ice goes below freezing, the amount of energy that the ice can absorb before melting will increase by about 0.3%. A large amount of energy is required to transition the ice from solid to liquid compared to the amount of energy to change the temperature of the solid water. So at 25 degrees the ice will require ~2.1% more energy than 32 degree ice, and at 0 degrees will require ~9.6% more energy than 32 degree ice. From my limited knowledge of heat transfer, I think the actual amount of extra time the ice will stay solid will be marginally less than these calculated percentages (because heat transfer is a function of temperature difference, so having colder ice means that it will draw in the ambient heat faster.) For sure, you will definitely get a little bit of extra time out of colder ice, but I don't think it's enough extra time to really be fussed over.
And just to comment on the whole cube vs block ice scenario, I think the math should work out that there's barely any difference. If you compared cube vs block ice just sitting out on the ground, the block will definitely stay solid longer because it has smaller surface area, and the surrounding warm air will not be able to transfer heat as fast into the block compared to the larger surface area of cubed ice. But when you put both of them into the cooler, the inside of the cooler is just going to match the temperature of the ice anyway, so that convection doesn't matter. The thing that really matters is the heat transfer from the cooler to the surrounding air, which is independent of the shape of the ice inside the cooler. But the more time the cooler spends open, the more the block ice should stay solid longer than the cubed ice.
John Harvey - lol
John Harvey that’s like saying steel can’t get cooler than 1,370 deg C.
Great information. :) Why do you have water in the cooler with the two jugs? Did the jugs leak?
I pack food in my cooler, not just drinks. I have best results with blocks of ice and no saturation of the food packs.
Dry ice under a barrier sheet the with holes in It (like a large, plastic cutting board with 1" holes drilled in it) does great for keeping mixed products like drinks, meat, cold salads, etc. cold, resting on top if the devider. Works great
. I have an Igloo 90qt. marine cooler, holds a lot, stays cold days. No Yeti needed for me. For just drinks I use about 35 lbs of ice... lots of drinks... no prob. I keep it shaded and am smart enough to keep an insulation blanket cut from a water heater insulator over the cooler. I'm trying to keep ice, not force melt it. :)
Give those tips a try in real application. You'll be surprised how well it works.
Thanks for the info! Will have to try a setup like this.
Yeah I was about to type same we use dry ice for hunting meat on road trips but you need a barrier or a rack sit the dry ice up above everything or below with barrier them sit items but dry ice is a packed cooler you can't rock it for a 12 pack in a 45qt
I would have included 4th cooler with frozen gel packs. That's really the alternative to dry ice.
Those barely last from morning to lunch break in my experience
It looks like lifetime updated the 55ct weather stripping/ gasket to match the 28ct and 77ct. I wonder how much of a difference it would make being that the gasket is on the lid compared to it being on the base - thank you
To keep things cool using dry ice, layer the dry ice under cardboard and put regular ice on top of it. Extends that ice by 2 good days doing that and nothing freezes.
What about the cardboard as ice melts? You remove this or it gets wet?
@@CoolersOnSale yep, it gets wet but I just leave it in and throw it out after my trip. I just used a folded over old Amazon box. I set this up in a 60-100 quart cooler. Don't know if it's worth it in a smaller unit. As this process takes up about 2-3 inches space in the bottom of your chest.
Use foiled bubble wrap as the barrier.
i use a thick towel on top of the dry ice. didn't know that cardboard worked too.
How did the gas from the dry ice cooler escape? I assume you did something to make sure that cooler wasn't air-tight, am I right? Great video, very helpful. Thanks.
They opened the cooler during the test to simulate real world usage
When we go camping, we put dry ice on the bottom and on top of that a few inches of cube ice. We always have to throw away ice after 3 days of camping. This combination worked the best for me.
Thanks for the video, been eyeballing the lifetime and debating it to for camping and kayaking. But after seeing the video I think we will keep looking.
Steven&Jessica Wheat if you haven't already gotten one, i say go for it. They're great
I bought an orca cooler, love it. Held ice for 6 days in the Midwest summer, made in USA with lifetime warranty
When a $97 cooler can do what a $300 cooler does. Yeah I'll take two lifetime cooler please
I've gotta refrigerator buried in the ground on it's back & keeps ice for 4to 5 days without the 100° weather here in AZ. IM building a shed on top now to shade the ground. I'm gonna try dry ice on the bottom then block ice in the middle then crushed up top. We'll have to see how that works here in 117° AZ.
make sure you cooler recommends using dry ice in it. Many coolers will crack with dry ice in them.
I got an Orca after watching 1 of your tests & the Orca didn't even come close to your results. Do you think my Orca is defective?
On the dry ice did you open then draining plug? It works for me when i go camping. But then again I take more then two cokes
If I’m using a cooler for packing out meat is dry ice the best bet? No drinks etc
So what about a combination of cubed, blocks, and a limited amount of dry ice?, Because I know a mix of 2 blocks and six bags (cubes) stayed cold for a week for me in a large igloo in the bed of my truck in summer in AZ, but the cooler just rotted away as the sun destroyed the plastic shell. I now have a much smaller cooler that won't stay cold for more than 2 days with 2 blocks and 2 bags of cubed... What if you added 3 small pieces across the top of the ice?
Not sure if you reply, i am wanting to travel with ice cream from OK to NJ I have a 55qrt Lifetime, will try ice work even if i have windows kept open?
Will you do a review on the blue ice, hard sides, like 3 x 5 x 1 ish size freezer packs please.
Hi there. Could I use just a small piece of dry ice aided by regular ice to keep things cooler longer, or would it still drop below 0?
I think it really depends on how much you use and if there is a barrier between the dry ice.
How about putting the water jugs with the dry ice. After 2 days, the frozen jugs can take over and cool for another 2 days.
That is definitely possible and how many people get more life out of their ice on long trips. You can extend the life of ice, but you'll want to be sure the dry ice does not touch any items that cannot experience a deep freeze (soda, beer, etc)
The dry ice goes fixed to the lid of the cooler NOT on the bottom next to the cokes! Lmfknao Hahaha
how about a video of frozen bottles, vs bagged ice, vs the gel block things?
ayo what about a combination of like a brick of dry ice on the bottom with a layer of normal ice cubes covering it? would that be a more viable way to idk keep the internal cooler for a longer period of time?
I was l👀king for the
Best Ice🧊
To use for A DIY swamp a/c...This DEFINITELY answered my question😁THANK YOU
MUCH ❤From
🌳Minnesota🌲
Dude with all the data you’ve collected the cooler manufacturers should be consulting you for r&d! 👍🏼
Agreed!
did you add water to the cooler with the ice blocks?
No, just the ice blocks/soda.
Could you just put a single slab of dry ice(still in bag) into the bottom of the cooler, then put regular ice on top of it, then your drinks etc on top of that..?.. seems like it would just keep the regular ice from melting without destroying your drinks...?
Do a test with dry ice wrapped in a towel vs. Dry ice with cubed ice vs. Dry ice wrapped in a towel with cubed ice over it.
Don't know if I agree that dry ice is good for keeping meat. While it won't explode like the carbonated beverages, meet can dehydrate so badly that it suffers freezer burn. Not sure how long that takes, but freezer burned meat loses a lot of its flavor.
Thoughts on a base layer of dry with crushed on top?
I think a combo can work really well. However, make sure everything you place inside the cooler can handle extremely cold temperatures. As you saw in this video the coke exploded with only 2 bags of dry ice.
The other way around works better. Dry ice on top, CO2 sinks.
Could you do a full review on this cooler?
Coming soon!
Waiting for the review. This sucker is cheap compared to the competition!
I need to see a review on this bad boy. Looks like too good of a deal to pass up.
Does this cooler have a hollow lid? I bought one and you can hear air coming out of the lid when you squeeze it. I guess I was expecting it to be filled with foam.
We noticed the same. We will be posting a video in the next week of the review. Also, others have asked if the cooler is "water tight," and we found the cooler to leak water if tipped forward or when carrying the cooler with a lot of ice melt.
We were quite surprised when we went outside to film the wrap-up of the video and when we picked the cooler up my leg got soaked!

I found out that the drain assembly may need to be tightened. Lifetime will send you directions if loose from factory. I am not referring to the plug.
Theres a cap on the inside of the lid. Remove it and fill it with low expansion foam
Can I keep meat in a cooler with block ice since it is not possible for me to get dry ice here
Yes, but it all depends how long you need to keep the meat frozen for and at what temp.
Salt your ice works best because it rushes the cooler to the temp alot of people don't understand ice into a 85degree cooler you left outside or bed of truck that cooler has to come down to create the perfect environment.
How about the block ice that you buy at the gas station?
Block ice without the jug.
I love ours
The 28q last me about 3 days max... I do landscaping so the cooler is always directly under the sun...
How much ice are you using?
@@CoolersOnSale between 10-20lb... I buy the 20lb bag but I have about 7 Gatorades at a time..
Should I presume the volumes of coolant were the same for each?
I might presume the temperature of the coolers were the same.
I don't know if you noted the temperature of the various coolants. Water ice can be anything below 32F, like -200F, and dry ice can be anything below -110F, like -200F !
Solid CO2 has a much lower specific heat than solid H2O.
I need to ship something in the summer time the shipment would take about 5 days!
Is there any type of ice packet that would cool my shipment for about 5 days ?
Can it be sealed? It real depends on what you're shipping. For example, if it's meat, and can remain well below frozen or if it is something else that needs to hover at a certain temperature.
Coolers On Sale , it is going to be chocolate .. it needs to be at least room temperature.. however, the weather where I’m sending it is about 100-110F’
Have you ever considered opening the cans of soda and taking the temperature of the beverage inside so we can see how cold they are from day to day and at the end of the test?
no
the difference of internal soda temp and the inside cooler temp after a few days will be about the same
if all youre putting in a cooler is drinks, dry is isn't the best choice. If you put a variety of food in, with an insulating layer between it and the food, it won't freeze everything
Agreed! Exactly what we wanted to show.
I wonder if you put dry ice in the bottom of a cooler and water ice on the top. How long would it last?
You are an idiot 🤣
Could you just use less dry ice?
Block ice is still best. Just don't use milk containers, as the plastic absorbed the milk protein. Use proper containers & after they melt, you have cold drinking water.
The plastic in distilled water jugs or used soda bottles will break down, so don't use for long term storage.
Gatorade bottles are thicker & last longer. I freeze water in these bottles & add to the cooler.
Song?
How bout just using a single slab of dry ice on the very bottom just to keep some real ice from melting, then put drinks etc on top of that...?
Heat rises. put your items on bottom. A layer of ice and/or dry ice, polar tubes, and a grate underneath your items. Then block ice and ice around and on top. Keep perishables and longer term storage like this. Have a separate cooler that will be opened frequently with drinks and other readily accessible things. The FREQUENTLY OPENED cooler should be packed the same, but without dry ice. Do not let water out unless you are done with the cooler. cold water will keep ice longer. Air inside the cooler will also cause ice to melt faster. Fill it up. even if its with frozen water bottles (the alternative to ice blocks).
NEVER TOUCH BARE DRY ICE WITH SKIN OR LET IT TOUCH YOUR FOOD OR COOLER. WRAP DENSELY IN CLOTH OR NEWSPAPER.
@@nomadbound9610 Since you didn't say don't touch with tongue i am going to try that! :) :O :P :)

You know about making "AC" coolers with fans ect why not use dry ass ice ya feel
If you use only dry ice, it will melt incredibly fast. The dry ice will turn to gas and be pushed out the cooler. If you wanted to do that, I think you need to put a base of dry ice and then regular cubed ice.
Do not use dry ice for Air conditioning!.. suffocation can result from.
So what happen to block ice lasting 2 days longer than club ice or maybe the weight was off
Can you explain what you mean by "block ice lasting 2 days longer"
Seen it online saying a block of ice last way longer than cube ice by 2 days. There talking these 7 days cooler test. So block were hitting the max but cubes were 2 days shorter.
But I think there a better way to buy coolers. I did on my yenti 65 Q.
That put your face close to the lid and hold it by the lid and drop it 5” of the top. Try all cooler even diffrent model. The best seal goes dump
Fummpp and the air get pushed out. You feel it. Other goes bump or bang sound of rubber hitting rubber and feel no air escapes.
I brought the best sounding one. And I can put a 10 lb Walmart ice cube and use 1 cup ice ever night and it last 4 and 5 th day cold water.
That make sense in amazon on the same on all cooler some say it excellent Few say it ok. I think the seal isn’t 100% level the same
I've only seen dry eyes used with Styrofoam coolers It can burn you on contact You usually also want a barrier between your dry Ice and the product you're trying to keep cool Or I should say freeze I'm surprised you didn't break the inside liner of your cooler
So maybe less dry ice and a frozen jug. Dry ice should keep the jug frozen for the 2 ish days that the dry ice lasts. Then the jug goes on for 3 more days and you get a longer total time.
In other videos..
They suggest boiling the water first to remove air bubbles...
Would have been interesting to have a 4th chest with frozen block ice with air removed and the ice elevated above the melting water
How do you elevate the block above the water?
Coolers On Sale
If you're not driving around a plastic container upside down with holes and or groves..
If you're not drinking the water..
Home depot foam layored with a pocket to hold the ice with groves to release the water...
Is how i plan on trying..
My experiment is going to be
A good sized ice chest..
With a box lined with 6 inchs of the closed cell foam in every direction..
To put the chest in...
Should help
But how much...
And using store bought ice blocks...
To simulate two week camping trip..
Maybe add salt to your ice blocks. The salt will lower the freezing temperature of the blocks meaning they will be colder. You would have to experiment with how much salt to add.
It would lower the temperature, but also melt the ice faster. Salt doesn't change the total amount of heat energy in the system. This could work out if you want to bring ice cream to the beach and don't mind if all the ice is gone in a few hours.
What about cubed with chopped ice?
Makes very little difference, if any.
You should try it when you salt down the ice
We've tried this and it has made little to no difference.
@@CoolersOnSale last time i tried that half my cans exploded and the other half were salty
Try a combo of dry ice and wet ice. Dry ice on bottom with a 2 inch layer of wet (cube) ice on the top.
Will add this suggestion to the list!
For the dry ice should i open the bag or leave it close
I left mine in the bag. Most bags should be vented (have a hole or two) in them.
Also place newspaper on the bottom of the cooler, leave the hole on the side open, so ventilation will keep it from exploding things, place something like foam, or more newspaper on top of the dry ice as well, to not over freeze things.. always keep your milk, cheese, and other items you don't want frozen solid on top of all you other stuff
I like the cubed ice, you can drink the water after
dunno used dry ice on stuff that's supposed to be frozen in the first place not pop and such.
You're definitely right. However, some people wanted to see the difference between the different types of ice. Needless to say,... we popped the idea on using dry ice for every day items.
Should wrap the dry ice
Any reason why you chose the lifetime cooler for these test?
Yes, because we had 3 identical Lifetime Coolers.
Wouldn't dry ice blow up?
Hated my lifetime cooler was using it in my semi
Why?
So why don't you just throw a little dried ice in with the other ice?
🤣 what a stupid comment!
These are 7 day coolers, why didn't the ice keep for 7 days but less then half?
Because those numbers are based on a full cooler of ice. See this test here: ruclips.net/video/JuHQxVFlciI/видео.html It did last 7 days
Live Free or Die no shyt huh?
The coolers were not full. 7 days with the chest FULL of ice.
pop the tops, drink a bit, no mess. Bob
Look for dry ice u put news paper on the dry ice then put above it the drinks
Well if you kept the dry ice wrapped to keep it at 40 it would be the better choice.
You used three times the dry ice, ???
The test was by weight. The same weight across all types.
Calibrate your thermometers. Ice can not make things colder than 32 degrees and you stated 27 degrees on the first cooler.
But the drinks can, which may attribute to the -5 difference.
dry ice dirty little secret; it don't last as long it seems
Agreed.
I think you should re-do the tests and don't open the lids at all. Since you have remote thermostatic sensors to show the temp. when Ice goes away and say you stop the test when internal temps goes over 44 degrees. Also, when I use dry ice in my Yeti, i put a thick towel over the dry ice and it only freezes what touches the towel. the rest just stays cold. It also lasts longer with the towel. It still does not last as long as ice. Thanks for sharing your review!!
How can help
What do you need help with?
So, what happens if you use less than 7# of dry ice? Perhaps it was just too much for the space?
Anticipate deez hahaha
Hahaha 😆. Good video though
another vote for salt ice test
so even if you buy a $300 cooler, it still works just as well as every other cooler... 41 degrees isn't even cold enough to keep food from spoiling. that's not worth showing off....
Jacob Licht these coolers are 90 bucks
