Hey guys welcome back, thanks for joining us today on the king of random in the past We’ve done several experiments with dry ice and we’ve had two viewers Give us suggestions of other things to try with the dry ice Daniel milage ask How does liquid nitrogen compare to a cooling bath of acetone and dry ice? YouTube user like ‘whoa says put dry ice in your backyard foundry so like whoa and Daniel mileage today we’re going to be doing two experiments using extreme heat and extreme cold the first thing we’re gonna try is using some dry ice and Acetone to make a supercooled liquid that you can use for some experiments if you’re having a hard time getting some liquid, nitrogen Dry ice is extremely cold, it’s approximately 100 9.3 degrees Fahrenheit below zero Acetone doesn’t freeze until one hundred thirty nine degrees Fahrenheit below zero so we can put dry ice in acetone it will Supercool the liquid down to the temperature of the dry ice but it won’t freeze we don’t just want to mix the two together So first we’re going to use this cup to create a barrier between the acetone and the dry ice for a first step Let’s take a drill and poke some holes in our cup I poked a lot of holes into this cup because I want the acetone to be able to flow in and out of it easily Next we’re gonna break up some of the dry ice and spread it all around the outside of the cup All right now load these all up all around our cup Our glass bowl is whining That’s the the dry is vibrating in very small movements all around the glass Just sounds like it’s complaining The next step is to pour your acetone down into the bowl And it should fill the cup as well as all the way around the dry-ice Force them directly into the cup to make sure it’s getting in there You go lots of bubbling going on I’m gonna try adding a little bit more dry ice as well Some of it seems to have a sublimed off from the heat of the acetone All right now we have a bath of extremely cold acetone That’s fun and in the middle because we have the holes in the cup We have a spot that doesn’t have any dry ice in it So we don’t have to worry about whether things are coming in contact with the dry ice all right watch What happens when I stick the tip of my glove into the acetone? That’s very very cold it actually makes the Nitro of my glove get a little bit stiff just from freezing it so much Let’s see what happens if we freeze a carrot Please note never use this cold acetone bath on anything you’re going to eat acetone is toxic and not safe for consumption All right care it into extremely cold acetone this acetone should be about a hundred and nine degrees below zero Fahrenheit Here goes It’s boiling in a similar manner to the liquid nitrogen when you pour it in the heat from the carrot is Heating up the acetone quite a bit. Hopefully the dry ice is keeping it nice and cold Set that in there for a minute All Right our carrot looks pretty good and frozen What I’m going to do at this point is take it out and smash it with a hammer to see if it shatters the way We expect a really frozen piece of produce to do quickly before I try that let’s make it control by smashing an unfrozen carrot 3 2 1 That kind of exploded a little bit more than I expected it to carrots aren’t super squishy, so I guess it makes sense We’ve tried smashing the unfrozen carrot. Let’s see how the frozen carrot handles listen to that That is not the sound of normal carrot 3 2 1 oh My gosh That is a very Frozen carrot, holy cow that sent shards. I mean the other the unfrozen carrot like broke apart would this like explode listen to that That’s a carrot it’s shattered to I heaven right there bluey Is ice carrot Now we know what happens if you freeze a carrot in acetone That’s over a hundred degrees below zero next I want to try and experiment with a rubber band When rubber gets too cold, it loses its elasticity meaning it won’t stretch out But it also means if it is stretched out it won’t contract back in and that’s what we’re gonna try and do today What I’m gonna Do is take this rubber band fit it on the end of the bamboo skewer and stretch it out and while it’s stretched I’m going to dip it into our freezing cold acetone. Let’s see what happens a little bits of carrot floating around in there, but that shouldn’t cause any That’s probably pretty good and cold already it stopped bubbling let’s take it out and see what happens if I like over the river band Look at that the stretched out portion is staying stretched out And then as it warms back up it regains its elasticity as it warms back up this time I’m gonna see if I can pull the rubber band out and Immediately try and bend it and see if it will break in theory It should be able to get cold enough for that but it might just warm up too fast And I’m not able to get it alright. Let’s see what I can do here There it goes Snapped a rubber band in half and now it’s already warmed up enough that it’s starting to be stretchy again. Let’s try that again Broken I think at this point the responsible thing to do is to put the whole rubber band ball in and see what happens Hopefully the acetone is getting in between the rubber bands and down into the middle so it’s really freezing it all the way through Alright, let’s see if I can take this out and see if it has any bounce left to it at all I bet it doesn’t really have any That sounded like a rock put this back in for just a second case. It’s warmed up then we’re gonna try hitting with a hammer One two three well Bits of it broke off I did shatter some parts you can see little destroyed bits of Rubber band just sort of sitting around their impact marks with a hammer hit, and I think as this warms up this is gonna start peeling away a lot more as One last experiment with our freezing cold acetone and dry ice I’m gonna see what happens if I pour a little bit of water into It genuinely have no clue what to expect here So I think the water dispersed in the acetone, but it also froze So I’m pretty sure what we’re seeing there are tons of separated individual little ice crystals in a pour some more in That just kind of builds up on the sides here weird slushy I’m guessing that’s a mix of acetone and water It certainly smells like a stone wool That is spraying everywhere isn’t it? Now we’ve tested making a cooling bath that takes acetone down to over a hundred degrees below zero Let’s see what happens if we take dry ice and put it in our backyard foundry dry ice is composed of carbon dioxide So it’s possible that as it heats up and starts turning into a gas it will put out the flame That’s one of the things you’re gonna find out, and if it doesn’t put out the flame Let’s see what it will do Our foundry is nice, and hot let’s see what happens when we put in our dry ice Looking at it so far. It’s smaller It’s still extremely cold of course Other than that it doesn’t look like it’s doing anything really special from the heat The fire in the Forge doesn’t seem to be affected by the carbon dioxide I think that there’s enough flow from the pressure of the propane that it just blows any excess carbon dioxide right out the top Let’s see if it makes any difference to put the lid on There’s our dry ice down in the foundry with the lid on it looks like it’s glowing orange, but I’m almost positive That’s just from the ambient light lighting it up Well there it is it hasn’t seemed to change much Except that it’s smaller so I’d say the heat does make it dissipate faster, but Nothing else is really happening to it Well, I’m going to try something else I’m going to try heating up these tongs until they’re glowing red hot and then touch that directly to the dry ice All right, let’s see what happens Well not a lot really Not a lot happened, I thought it would do a lot more I thought the red-hot metal might melt its way through the dry ice kind of like it does with normal ice But it just cool off the metal and barely left a dent in the dry ice Let’s throw the rest of it in see what happens Well all of our dry ice is gone It didn’t put out the flame it didn’t put off a lot of vapors like it doesn’t put it in hot water It just sort of sublimated into nothingness that whole block took about 10 minutes to disappear in our furnace Which is much faster than if you just left it sitting on the counter, but it’s not very enjoyable After pouring all of that water into our supercooled acetone bath something interesting has happened. It’s turned into a slush So I think this is about half water and half acetone So I’m going to scoop it out put it on a brick and light it on fire Not entirely sure what’s making it bubble like that here goes Oh, it’s actually on fire. It’s just acetone burning so it’s very clear. It’s hard to see Well that is burning right now Burning snow. You don’t see that every day It’s still really cold it’s on fire, but it’s freezing cold like if I touch part of it It’s very cold to the touch, but it’s on fire It’s freezing cold and on fire at the same time that was freezing my hand and burning my hand Different parts of my finger at the same time. Oh and now our acetone is all just running off and pouring off and We’ve used this brick for some colored smoke powder before and the acetone has been pulling that off of the brick And so we’re getting this pink stain as it runs There you have it two experiments using dry ice one a method of making an extremely cold liquid bath using Acetone the other putting dry ice into our backyard foundry with the acetone bath we were able to supercool rubber and produce and both of them became very brittle and Lost all their elasticity when they were completely frozen in the acetone with the dry ice in the foundry it turned into gas Faster than it normally would if it were just sitting out on the counter But it wasn’t really very entertaining nothing spectacular happened the co2 wasn’t enough to put out the fire. It just kind of Disappeared a special shout-out to Daniel mileage and likewho for your suggestions on what we should try check your youtube inbox We’re sending you 25 bucks if you have any ideas for any Experiments or projects you want us to try let us know down in the comments if we end up using your idea will send you 25 dollars acetone is easily available at most hardware stores, so this is an experiment you probably can try at home Just be sure you wear protective gloves and eyewear at all times Thanks for joining us today for these projects and we look forward to the next one talk to you then It’s bouncy again, this is cleanup Don’t let on fire Three two one hang on I’m going to put my safety glasses on Hey guys Did you know that we’re on Twitter Instagram and Facebook as well all at the king of random and every platform has a different purpose So go scroll through the histories check out what we’re doing. I’ll see you there

    If it was possible. What would happen if you dropped dry ice into molten lava? Would it cause explosion or create huge steam?
