When it becomes colder can you do an experiment to see whether or not coating your sled with hydrophobic material increases the speed of the sled. I hope this can be turned into a video!
Ski’s work on the principle that there’s a small pocket of air between the ski’s themselves and the snow and that’s why they can go so fast. I don’t know if making them repel water will make them go any faster though. Would be a good experiment to see what happens, great question! 😊 (I think it’s the same principle for a sled or ski’s, correct me if I’m wrong please) Edit: people also use wax to make the ski’s go faster and wax basically make it hydrophobic, so I think you’re onto something here. I do think that making it hydrophobic will make it go faster!
This reminds me of a Phineas and Ferb episode called "Unfair Science Fair". There was a part of the episode when Doofenshmirtz said that he would always lose to a baking soda volcano. He built inators but he lost to a baking soda volcano. Even at poetry,he lost to a baking soda volcano. ._.
Wow! I'm surprised that so many people didn't do that in school. We usually do it, and also perform catalytic combustion of ammonia with chromium oxide that formed during volcano. It looks very nice, when hot particles of chromium oxide fall in flask filled with ammonia, and glow, due to ammonia combustion of particale surface.
I remember in grade two that a high school teacher showed us this reaction, stuck with me my whole life as one of the most beautiful things I ever saw.
I remember doing mine many, many years ago, and using potassium permanganate with a few drops of glycerine. Gave a really nice flame reaction with some glowing "lava" at the end :D
I've got 8 pounds of potassium permanganate lol, that's a fun reaction to play with😁. I also take a 100ml bottle of glycerin along with a 1/4lb bottle of permanganate whenever I go hiking, it's a sure-fire way (no pun intended lol) of getting a fire going in an emergency, it works in all weather conditions and is super fast.
We did this making zinc sulfide when I was a kid. A big pile of zinc dust and sulfur will make a nice volcano for you too. Bright as all get out, lotsa smoke (gotta have smoke with a volcano!), and heat. Plus the remnants are pretty benign. And it glows in the dark.
I used to do this for my 7th and 8th grade students, too. And I also used a coil of magnesium as a fuse. I didn't do it often, but it was so dramatic that it served to introduce the upcoming units on physical science. I didn't really understand the reaction very well and didn't know it was dangerous back then. Still, I stood back a ways. :)
Fun story, back in middle school, instead of doing the basic baking soda and vinegar volcano i used alcohol and used pressure from a ballon. nearly burned down the project of my classmate after that.
For me the ammonium dichromate volcano was demonstrated at school a few times, earlier in high school science class and then later in senior school chemistry class. There were no fume hoods or serious safety measures taken. However, this was back in the early to mid eighties before the dangers of hexavalent chromium were fully appreciated. I remember using both the chromate and dichromate potassium salts in chemistry lab experiments as well, which certainly would not be allowed today.
That was a nice video, thanks! Back in the 70's I made volcanoes too. I used a mixture of Kalium (Potassium) Nitrate and sugar, the right amounts are easy to calculte, so I won't calculate it while writing this comment. :-) I put the mixture (about half a kg or more maybe) on sand. Then i piled more sand on top with a paper tube about 50cm long filled with the mixture going inside the sand pile to its top. When we ignite the volcano after dark, initially looked like a not so violent volcano. But when the bigger lump deeper in the sand ignited wo got a wonderful show of a violently erupting volcano. We also made volcanoes having multiple pockets of those "magma piles" connected with paper tubes to the already ignited core. There is no danger of actual explosion altough hot sand etc. may fly a few maters distance. Why not try it youself and let us see how it looks?
I had the same thought, and I wonder if the heat transfer by contact would sustain it at varying levels of vacuum. That's a good idea for him to try sometime. Might need to keep the pump running to remove the water and nitrogen, and use a filter to prevent chromium oxide from clogging it. But I'd definitely like to see that.
Good grief, I was so enamored on 3rd grade after seeing the teacher do the ammonium dichromate thing on a miniature volcano model that I did the same at home sometime later on. Made a papier-mâché volcano and my mom helped me get the chemical. Now I find out it’s carcinogenic- which may explain the toe that grew out of my ear in 4th grade
I tried calcium nitrate + sugar when I was young. Really hard to get started but when it was burning I could shovel sand over it and it became a volcano.
Your heading could be a bit more accurate: "The Volcano Reaction You Didn't Do In School, if you are younger than 50." I did the dichromate volcano in 1966 in tenth grade world geography class, but that wasn't really satisfying. I decided to also do it in chemistry class. Mr. Overton had just left the room, so Julius and I grabbed the dichromate bottle and poured out about the same amount you used in this video. The chemical reaction was powerful enough that even we became a bit worried. Right after it ended Mr. Overton returned, saw what we had done, and understandably became furious. Apparently our mutual guilt was sufficient punishment, as not only were we not suspended (which we could have been), but he chose not to even send us to the office or detention. It could of course be argued that he didn't want to face the wrath of the school administrators, but he was a very responsible and dedicated teacher, and I'm sure he made the (correct) judgment call that our observing his anger and disappointment that was directed at us was a sufficient life lesson in this instance.
@@insectbite1714 Um, as soon as the phrase "proven fact" shows up, it's kinda like the phrase "I'm not a racist," it raises a red flag. Insect Bite, please show us your source for your proven fact.
I kid you not, I’ve been looking for this demo for decades! I saw it as a toddler, then spent years searching for the chemical details. But because the demo was stopped and replaced with the inferior baking soda/vinegar, no kid lit for science referenced it anymore. This is the first time I’ve seen it since I was too young to understand all the words. So satisfying.
I just remember When we tried this Experiment at school (with a less amount and at safe box) my friend came through and blew it up. It was a dangerous but funny experience for us lol
Now THIS was the kind of volcano we used to make and burn as kids in the 1960s in our backyard. We would build and paint a "Volcano" out of papier mache, then fill it with an "orange powder". It produced an identical effect as thus. Including the dark green ash spewing out. It was pretty cool!
might look different due to the lack of air around it, but shouldnt have too much of an effect. it might even go marginally faster due to the fact that theres no air to transfer heat away from it
I had no idea. I think was back in fifth grade, one of my parents friends, chemists, suggested building a volcano for a science project. We use this chemical with no safety precautions whatsoever. I had a little amber glass bottle with a screw top lid full of probably three or 4 ounces of the stuff. Built a volcano out of cement with a little well at the top, poured in this red powder, lit it with a match and the green ash came spewing out. There's nothing like the 60s for totally unsafe but really cool science projects you could buy over-the-counter. Someday I'll tell you about how the chemist friend of the family got me 20 or 30 "safe" chemicals in 8 ounce jars so I wouldn't have to buy those expensive little tiny bottles of chemicals for my science kit.
The entire class did this at my school. The room was green afterwards. It probably wasn't the best idea to let the students take their own dichromate as there are varied interpretations of "enough to cover a penny" :D
dont think the fumes should be an issue, unless i wasnt paying attention. nothing dangerous once it reacts, and it doesnt give off fumes prior to reaction
@@ciarangale4738 The really toxic part is the chrome 6 ion - thats really toxic and carcinogenic. Once decomposed to presumably chrome 3, its no where near as nasty. As long as you didnt breath in the powder, you're good.
@@spwicks1980 well the last words you said are...umm ... Concerning. Kids these days want to snort all kinds of powders, as long as they can get their hands on them 😂
On YT anyone can make a BS copyright claim & demonetize your video & YT don't seem to give a flying F so if your videos 30 minutes long that can mean you just did a months work without getting paid. But if you split it into six 5 min videos & a couple get demonetized you still will get paid for the others
This is SO cool, we actually did this in highschool in the Netherlands, about 35 years ago. Now I know the name of that mysterious orange powder! We heated it in a test tube causing the ash to eject out of it. It was just done in the classroom, no safety measures like gloves whatsoever. No idea the stuff was that dangerous....
I wonder what would happen if you put the ammonium dichromate in a fishtank, cover it up with soil, and then apply heat to it electronically. Would it burst through the soil spewing ash like a real volcano?
So glad when I was in grade 5 1985 we had a science teacher that did the volcano demo with this stuff, only she put it in a clay volcano shell for it to erupt out of. 😁🇦🇺
Uh, I actually DID do this volcano reaction at school. I had to have the teacher light a match to initiate the reaction, but this was literally my elementary school science project.
It makes stuff that looks like lava/ash in a cone, but volcanos aren't chemical reactions turning the volcano into the eruption. The bicarb/vinegar thing is somewhat more realistic, but still just illustrative.
@@letsmakegadgets6899 Right, the oxidiser is part of the propellant in the shell. So it produces it's own oxygen as part of the reaction. That said, has anyone fired a gun in space? I know a couple of the Russian space stations (Salyut?) had guns mounted on them, anti-aircraft cannon taken from actual aircraft. Never fired in anger but I wonder about accidents...
Yep. I’m pretty old skool, so I’ve seen this done IRL, as well as putting my hands in mercury and getting my hands covered in concentrated HCl. Oh, the good old days. 🥰 And still here to tell the tale. 😊
My HS science teacher did this demo when I was a freshman, we all loved it lol. Of course that was 20 years ago before schools stopped making the learning process interesting. Also, the by-products of the reaction (chromium oxide, or Cr203) can be used to make a chromium-based thermite, just add 30% by weight of aluminum powder and ignite it with magnesium ribbon. Pure Chromium metal pellets can be collected after the reaction occurs, it's a neat way of getting Chromium samples for your element collection.
In my school, the chemistry lab is just a show room no one is allowed to touch except when an official comes to check up.Only got into chemistry after getting into channels like this.
Joke's on you, our teacher demonstrated this like twice a year for four years during our chemistry classes. If you sat too close, you would get chromium oxide on you.
Do it in a vacuum chamber, would be cool to see a 'fire-like' reaction there. (use a nichrome wire or smth to ignite it) Just have to make sure that you put a filter before the intake so you dont accidentally get the chromate in there.
I don't see anyone making comment on the end product of the reaction, so I'm chiming in - that green fluff left behind is chromium oxide, Cr2O3. Pretty harmless and inert compound, and when you mix it with oil (like boiled linseed oil) to a thick paste/ semi solid consistency you got a metal polishing paste suitable for virtually any metal - steel, silver, brass, copper or gold (although cerium oxide apparently is bit better for gold).
I actually did this in lab last week and used the chromium(3) oxide to make anhydrous CrCl3 (very pretty purple color to it) but messy reaction. Make a phosgene byproduct and have to use CCl4 so its not ideal.
Wonderful video, I'd never seen this decomposition volcano before, thank you. Also, MicroCenter is amazing I really prefer to send people there for computer parts and repair if possible if they don't send their computer to me, or I cannot repair remotely.
We did it at school! We also pipetted all sorts of carcinogens and strong acids and alkalis by mouth, in Chemistry lessons, and played with solutions like Millon's reagent in biology. We used to take old British pennies - George V 1d coins were the best for this, precipitate mercury on the surface with the Millon's reagent, and pass them off as half crowns for a profit of 3,000%
Our chemistry teacher did this for us. It's so cool. He even added some magnesium powder so it had more shiny reaction. He did it in an isolated chamber with a vent and told us to stay back. So the toxicity wouldn't hurt us.
I wanted to ask something.... why does honey "wiggle kind of stuff" when you drop it in a plate. The same thing happens with water.... like if you have a really thin laminar flow from a tap and bring your finger near the tap in the flow of water
Not only did we do this reaction at school, ammonium dichromate was part of a number of children's chemistry sets during the 1960s, and was freely available.
When it becomes colder can you do an experiment to see whether or not coating your sled with hydrophobic material increases the speed of the sled. I hope this can be turned into a video!
Hydrophobic material on a snowboard sounds exhilarating....I wonder how it would affect control
Also coat a rock or stone in hydrophobic material and toss in in the water

Joke's on you, our teacher demonstrated this like twice a year for four years during our chemistry classes. If you sat too close, you would get chromium oxide on you.
I like the reaction of it caused by burning it a little. :D
Also,the only volcano related experiment I did was the lemon volcano experiment.
Love from INDIA 🇮🇳🥳❤️

Do it in a vacuum chamber, would be cool to see a 'fire-like' reaction there. (use a nichrome wire or smth to ignite it)
Just have to make sure that you put a filter before the intake so you dont accidentally get the chromate in there.
Wow
Gg your first
Wow
gg ur first
FIRST IS NOT CO
Fun fact:
Chromium oxide is the contaminant (at about 0.5-1% by mass) in aluminum oxide that produces rubies.
Vinegar and Baking Soda volcano: who are you
Ammonium Dichromate volcano: I'm you, but stronger
I don't see anyone making comment on the end product of the reaction, so I'm chiming in - that green fluff left behind is chromium oxide, Cr2O3. Pretty harmless and inert compound, and when you mix it with oil (like boiled linseed oil) to a thick paste/ semi solid consistency you got a metal polishing paste suitable for virtually any metal - steel, silver, brass, copper or gold (although cerium oxide apparently is bit better for gold).
PLEASE show the volcano in the dark! It looks so cool!!
thank you very much for getting sponsored by Microcenter
I actually did this in lab last week and used the chromium(3) oxide to make anhydrous CrCl3 (very pretty purple color to it) but messy reaction. Make a phosgene byproduct and have to use CCl4 so its not ideal.
Man I LOVE this channel!
If this dude was my science teacher, I would have loved school
Wonderful video, I'd never seen this decomposition volcano before, thank you.
Also, MicroCenter is amazing I really prefer to send people there for computer parts and repair if possible if they don't send their computer to me, or I cannot repair remotely.
My science teacher did exactly this as a demonstration on our first science class at high school. I always wondered what substance he had used.
We did it at school! We also pipetted all sorts of carcinogens and strong acids and alkalis by mouth, in Chemistry lessons, and played with solutions like Millon's reagent in biology. We used to take old British pennies - George V 1d coins were the best for this, precipitate mercury on the surface with the Millon's reagent, and pass them off as half crowns for a profit of 3,000%
Combustion and or entropy debunks the big bang theory! I love your videos!😁👍🏽
No
Our chemistry teacher did this for us. It's so cool. He even added some magnesium powder so it had more shiny reaction. He did it in an isolated chamber with a vent and told us to stay back. So the toxicity wouldn't hurt us.
Yet he doesn't worry about 5 G which is WAY more toxic than that expirement. 5 G weakens immune system that's why they hide 5 G
This reaction I have did in my school. But now I know the exact reason behind this.
Wow that's epic!
The only thing it lacks is hot liquid pouring out, but this looks almost exactly like a real boiling volcano.
Please put this stuff in a model volcano. It would be pretty cool.
I was expecting the reaction being done in the vacuum.
We actually did do the ammonium dichromate volcano back when teachers didn't care whether their kids died of cancer.
I wanted to ask something....
why does honey "wiggle kind of stuff" when you drop it in a plate.
The same thing happens with water....
like if you have a really thin laminar flow from a tap and bring your finger near the tap in the flow of water
He became weird after going near that 5 G cancer tower in one of his recent videos.
Not only did we do this reaction at school, ammonium dichromate was part of a number of children's chemistry sets during the 1960s, and was freely available.
Thanks for the video.
And so - even if you attempted to smother it to "put it out" - it wouldn't stop "decomposing" ?
You should try to put some slim in a freezer, microwave and vaccum chamber
All of these experiments could be so cool to watch
Is there a way to stop this reaction? Since you can't suffocate it, it would be pretty dangerous, I would think.
High schools sometimes do demonstrate this although of course the students aren't allowed to handle it
