How Does It Work? - Lava Lamps
HTML-код
- Опубликовано: 27 апр 2010
- A lava lamp (or Astro lamp) is a novelty item used more for decoration than illumination-the slow, interesting rise and fall of variously-shaped blobs of wax is suggestive of lava, hence the name. The lamps are available with a variety of styles and colours of wax and liquid.

How do you possibly dislike a video showing how a lava lamp works? Why would you CLICK a fucking video titled *How Does It Work? - Lava Lamps* and then DISLIKE the video when it *LITERATELY* shows you exactly how a lava lamp works AND why it works...?
BossBunny.Com People are purposely retarded.
***** HAHA your name! XD
BossBunny.Com seriously, people gunna hate and a potato gunna potate
+Boss Bunny answer is their skulls for grey matter have grey bricks
why was this recommended to me. like really. its late, im tired, my egg exploded in the microwave, and im watching stuff about lava lamps on youtube.
Just wax and water..? I always thought it was a bunch of chemicals... Does this mean I can make one?!?!?
***** well now my dreams are dead. thank you.
thank you
i shall now attempt to make my own lava lamp
I just restored my cloudy lamp, using instructions on RUclips. I used distilled water and epsom salt. The instructions also called for clear dish soap. But I didn't need the soap. Just the water and epsom salt.
@@markmarkofkane8167 I tried that after my man friend was mucking about and my birthday gift lava lamp bounced onto the floor, i bought a bottle of distilled water and epsom salts from eBay and followed instructions by pouring water from the lamp down the sink and rinsing the bottle out .Best to put lava lamp in fridge so the wax is rock hard before draining cloudy water down sink though.
Carefully poured distilled water into lamp and then a few teaspoons of epsom salts then turned it on to heat up then added some ecover washing up liquid , i just could not get the formula right but what i have found out since is it is only tap water and clear washing up liquid.
@@2011williamandkate I guess results vary depending on the brand. Mine wasn't the Lava Lamp brand, but another. But it still is clear, and works well for me.
This is perfect for demonstrating the concept of convection. Thank you.
Anyone else looking at a lava lamp while watching this?
Yes :D
yeah :D that's the reason I watched this Video ;) I watched my Lava lamp and I wanted to see how it works :D
yes lol
yes !!! haha lmao xD xD
Ishoam Tsaunin omg lol me
One of the best videos I have ever seen on how the Lava Lamp works!!! It's cool how it was shown cut in the middle for a better understanding of what's in the inside and to show how it works. Very Nice!!!
i wonder if its possible to do it like a whole lava lamp wall or to try it with an aquarium?will it work??
saskocar it would probably work with proper bulbs i dont think the container has much to do with how it moves
+saskocar The size of the the wall would cool the wax before it even got halfway up the wall. If you could find a way to replicate the heat spring effect across the whole bottom half of the wall, you might be able to. Same concept with the aquarium, and if you made it double walled you could even put fish in it with the proper construction.
Je suppose que cela pourrait être possible. Ce serait vraiment cool!
better looking at the lava lamp effect projector lamp
Amazing! But why would anyone dislike this?

It probably has something to do with the price of some lava lamps! The technology behind them (lamp, water, wax) has been revealed as being cheap to produce, but some lava lamps cost a lot of money.. maybe people who paid a lot of money for a lamp disliked the video? 🤔
JmeJ83 who the hell is buying new lava lamps
HorlicksB4Bed absolutely. I once got ripped off at the used car lot and immediately disliked any video I could find that explained the principles of the combustion engine
someone would dislike this cuz they r a skl kid forced to watch this
maybe their lava lamp broke
I just got a lava lamp for chtistmas today.
Same here.
Same
Nice gift right? What clor did you get? I got green.
Cool, I got a blue one
BlackroseDN Black and orange.
That's pretty neat! I have my lamp going right now, and I always wondered how it worked. ^^!
Just loved the you explained!!!
lava lamps be lit
The question I had, which wasn't addressed in this video... Why don't the warm and cool blobs of wax mix with each other when they hit each other? That they bounce off each other is is by FAR the biggest reason a lava lamp looks so cool. I majored in physics, and I don't have a good reason why this happens... I would be interested in any thoughts you guys have.
Im not really sure but best bet is that it's because of the leiden frost effect?
You answered it yourself. It’s cause one blob is cool and one blob is hot. That’s why they don’t mix. The hot ones particles inside expand and go up and the cool ones particles tighten which makes it dense and go down.
I have always wondered how lava lamps work it is very fascinating
this really helped me learn about how lava lamps work
thanks for posting this video
i will subscribe to watch other cool videos from this channel
I love this just got a lava lamp and was curious and even tho I still don’t really know what that means but I really thank you for the video explaining how they work lol
Great video now how it works I've always wounded how it all works😌👍👍
just bought one.. had to know how it works.. hella facinating lava lamps are..
Woops! this video got me finished with me homework :P
Great little video
I enjoyed this video. Very interresting
excellent explanation in simple language .. Like
Watching this for school work, but I feel bad because the one he cut open is the one I have xD
yes
I got silver lamp with blue liquid and white wax
@@jesuscervantesj82 that’s the one I got!
very impressive :)
@Animalkisser I've used mine almost every day since 1967 and it STILL works fine! It's a collector's item now.
Nice video, but it only gets into convection and the density cycle (I already knew that part). I'd really like to know more about the membranes the wax forms to keep it in discreet globs, instead of simply wanting to mix with the water. The wax blobs' surface integrity eventually becomes so high that the globs vehemently resist absorbing into each other. They usually have to press against each other for several seconds or longer before they'll even think about absorbing in, and that's at the bottom of the lamp by the heat (at the top and center they're even more opposed to merging).
The surface tension also affects how easily globs split. In my larger lamp, it will create some fairly long filaments that don't want to collapse into their own globs until they're stretched very thin. In the smaller lamp, the globs like to split apart much more readily, so maybe the type of wax being used is different. The larger lamp is also much older (I picked it up used, and it works much better than the smaller lamp), so that may be affecting how the wax behaves.
I don't remember my chemistry very well, but I think someone once explained to me that water tension is caused because the bipolar water molecules line up and form a polarized surface. However, water droplets generally have a very high affinity for each other, easily merging together and staying together until they reach a certain critical size and the surface tension cannot fight the weight anymore. However, lava lamp globs are hostile to one another and don't want to merge easily (at least once the lamp has been running for a couple hours), and will even form water bubbles inside them and have a double or quadruple series of membranes creating distinct layers or pockets, all of which resist merging or rupturing for long periods of time. In that sense they're more like living cell membranes, and the proto-cells that presumably preceded life (yea yea, long stretch I know).
I wonder if a chemist could give me a basic explanation of what's happening there. I'm guessing it's something cool with the wax molecule's structure, but it could be the water or a mixture of water-was that forms at the surface...? Whatever the case, it would be fun to find out.
Thanks!
BTW I got curious again, and this time my google search turned up some more useful results:
72dynes.blogspot.com/2011/11/surface-tension-makes-lava-lamps.html
www.thenakedscientists.com/forum/index.php?topic=44573.0
So that's a bit on the chemistry, but it's still not much.
I've also been watching my lamp more. I do think there's more than just surface tension alone going on though, since the drops of wax don't like to recombine with each other easily the way water droplets do. I've looked closely at my lamp and noticed they never physically touch (except when the lamp is just getting going, which is when drops combine easily). There's a thin layer of water always separating the globs, and they slide right past each other with this layer of water greasing the surfaces. It takes some resting time before that water becomes thin enough for the two globs to touch and combine, or perhaps for some other physical process to take part.
Maybe that's normal for surface tension; maybe drops of less viscous materials, like water droplets in air, simply combine more readily. But I wonder if there's actually a polar, two-sided membrane that's a combination of wax and water that repels the same-poled surface of other drops, and that surface has to be punctured or weakened before drops can combine.
At least, that's what I think is happening. Lots of speculation currently. A chemist may be able to offer better information.
Thanks for sparking my interest again. ^_^
***** Maybe. I've seen neat stuff like multiple layers of bubbles within bubbles, which refuse to rupture even when the outer layer merges with another blob. It's cool to watch.
Thank you!
Does anybody else hear the Tony Hawks Pro Skater 2 menu music at 1:47 in the video??
I still have the lava lamp my grandmother gave me in 1985. Works perfect.
+Kristian Pritchard I don't know, when I was younger i'd try to take the top off, I couldn't get it off to see what the cap was under it.
Love mine!
that lamp is pretty cool
Anyone notice the theme song for that guy Katz in Courage the Cowardly Dog
I live in New York USA , but thanks for trying to help
I was caught off guard when he removed the top and exposed a bottle cap
bro
So coool! i like this video.
I live this lamp for many many yearling !!!
I still don’t know how it works. 😂
Bruh this is an explanation for children are you dumb bro?
Cool that sounds
amazing!!!!
Thank you for not making this a kids video so we can still comment on it
A new lava lamp needs a break in period, somewhere around 4 even 6 months of 8-10 hours a day of on time, 14 hours off. Eventually it settles into a smoother cleaner look
I have had a red and purple lava lamp for a year and im getting more soon : )
If I have a crystallized lamp, and foggy one, can I just pour the liquid from my crystallized lamp into my foggy lamp? I really need to know before attempting it.
ive seen no one else do this so *inhales*
ARCHEMIDIES!!!!!!!!
You can actually test this expansion of the wax in the lava lamps. Mark a line of the very surface of the water when cold, and then when it's hot the surface of the water is higher than when it is cold.
Its...actually THAT simple? Just wax, water, heat???
My god i've been missing out
He forgot to mention ... you have to change the density of the water to0 ...by adding slowly some dissolved salt.
I just found two of these badboys in my room the other day. Holy crap does my room ever look nice at night.
how much do they cost?? and.....do they need to be on to have the liquid moving? or just floating? or it will stay in the bottom?
nice what kine of materials did he used
love this video
Me too
Can this work with Iodine and a gas that is slightly more dense than iodine as a gas ( if you have an equal amount).
damn this is intricate i’m watching it for school
Watch you mouth for you get humped
much more simple than i imagined, I thought they were made out of rocket science and magic
I have NO lava lamp, but I WANT ONE!!!
They had a show like this in the U.S but with an American narrator, i loved watching this show but they stopped showing it. good video.
Tyler C How it's made
Yep cool show now they do dream cars
Yes, and it's mentioned at the last of the video, you genius.
Omg dude that's funny i know what your taking about lol nice one
definitely did not need to take so long to explain something so simple
Who’s here in 2019? xD
Oh and I have a “glitter lamp” not a lava lamp ;c
But it’s still sorta like a lava lamp
me, actually curious about lava lamps at 4:32am now might just buy one lol
r they safe to leave overnight?
Does anyone know what kind of wax it is, where we can buy it from, and how can we color the wax?
me too ,but i dont know were they sell lava lamps
What brand are these
What kind of wax is used?
Has anyone ever wanted to touch the "lava" inside a lava lamp? I have been dying to..
*Monday, March 30th, 2020. 4:05 AM*
No this was not recommended, no I dont have a Lava Lamp. I just randomly thought in my had tonight: "How the hell did those things work?". But now, I think I'm going to get a few again.
Good 'ol "lawr" of Principles.
and I was ironic, looks like the genius changed ;)
I know how a lava lamp works I just want to know how to get the bubbles like mines is some weird as star shape with some thing at the bottom
I just hope it works properly or at least makes more than just one bubble
I have that dark blue lamp on the left side
What type of wax
Cool
ok, but will it blend?
eeerr...i dunno, get a blender and a lava lamp and, let's try to make the wax and the water blend.
Do they ever get old and not work right?
Tech rad sent me I love it😍
Somebody has to be really high right now watching this hahaha
VeedddeeR me
Oh well. I'll get one someday.
Where I can by it
How expensive this ?
I actually figured it out myself 😂 by thinking that
I got my lava lamp yesterday i was just curious of there history
helped with my exam ty
Hou dou i make it ?
that answered my question
No video in the world that's popular can last a day with ought a dislike
+ChicagoRunner You really ought to learn how to spell out.
i had three of em a red one witt shiny things in it , a red one and a ultraviolet light lava lamp@TheCarvingman
I came straight here after watching The King Of Random's new video
Always been a mystery for me.
I just got a lava lamp, and I can see through the lava and there are lots of bubbles in it. Is this normal, or is there something wrong with it?
Generally happens when the lamp is ran too long. Many people leave them on 24/7 without thinking otherwise, but generally you only want them to run more than about 12 hrs, or the wax overheats and essentially cooks.
Uhmm doesn't water also heat up and become less dense?
but does it blend?
wait, you have one?!
when you got the same blue/green lava lamp.
1:13 augh the horror
WHAT your profile picture is sans skeleton but this comment was made two years before undertale? either you created undertale, the creator of undertale showed a picture of sans skeleton before, or you made a drawing of skeleton creature that coincidentally looks like sans skeleton!?!
@@chromosoze Remember, you can edit your profile picture
I mean, I figured that the bubbles got hot and raised, cooled off and fell, just like air does in real life
Is their a way to change the liquid Color in the lava lamp?
You mean like from green to orange?
change the water mixture....
+Danker Barrel Food colouring can be used to change the colour of the water. There's no issue with it, just be careful, one drip often is enough. You need to very carefully remove the cap (don't damage it) and rubber stopper, add a drip of colouring, wait for a bit, and add another drip if the colour is too light. When it is right, put the rubber stopper back, then the cap. It is most important that the rubber stopper is properly closing off the globe, else the water inside will evaporate. It goes without saying, but do this when the lamp is off.
What can u do when the lava sits at the bottom and dosent rise
Get a electronic candle melt it then pour it in a glass large enough but with a cap and pur water and youll have a lava lamp
my wax stays at the bottom of mine.. how do i fix it??
