Freezing 91% isopropyl alcohol to the temperature of liquid nitrogen, and testing it with fire. SUBSCRIBE- shorturl.at/adk02 FACEBOOK- shorturl.at/ilrH2
shellyellyo I don't know how much they'd actually change other than just burning. The Oreos I'd predict would melt and there's enough sugar in the cookies themselves to hopefully crumble apart.
This video was awesome, i loved the shot of the alcohol freezing over. The fact that you took the time to freeze it and play with it for our enjoyment then refreeze more and use your RHNB on it to conclude the video showed how much you can and obviously enjoy making these dope vids. Keep up the great work man
+TheAwkwardBanana I am not sure you can reach the triple point of isopropyl alcohol(The pressure required is listed as "?" in academic papers), and I know you most certainly cannot reach it at atmospheric pressure(comparatively ethyl alcohol needs 4 atmospheres pressure). I was confused by the bubbling as well, but I think I know what caused it. The rapid formation of ice crystals was forcing the dissolved oxygen out of the solution. Normally ice freezes from the outside in, trapping the oxygen bubbles you see in the center of normal ice in your freezer. Because this was freezing from the bottom up without the top being sealed let the gas escape, causing the bubbles we saw.
I'm p sure that the supercooled alcohol is way more dangerous than the liquid nitrogen, considering it doesn't flash evaporate on contact with skin, and it seemed VERY gooey and sticky.
Love these videos guys. You certainly make science more interesting than I recall. How knew you could freeze alcohol and really amazing seeing it in a putty like state as it started to melt. Keep them coming love the big reactions the best
When I saw the title I thought "how does one freeze alcohol?", and then he whipped out the liquid nitrogen. I should have known better.. Oh man it was so cool how the alcohol became all gooey as it started to melt at 1:30, great video as always!
Woah, I had no idea alcohols (or at least Isopropyl alcohol) become viscous when supercooled! That's actually pretty amazing. I was expecting to to go directly from liquid to solid similarly to water.
Why was the propanol so viscous when it started melting? Is it actually that viscous in its liquid state at its normal freezing point or did it gradually soften with increasing temperature because it underwent the glass transition on freezing so it was actually a supercooled liquid when it was viscous that had the potential to nucleate the crystalline soild state?
can you make it with 100% ethanol? how does it look like when it freezes? also i have never seen pure HCl liquid. I mean no aqueous solution but as molecule, in liquid form. It can be done just applying pressure without cooling it down yet I never seen it
Why is it bubbling while it's freezing? Also, what's in the alcohol that's giving it the consistency sort of like glue when it's semi-frozen? This might be one of the most interesting ones.
How big is RHNB? I always assumed it was like the size of a tangarine, but then we saw that little flower bucket a while back and now we got a glimpse of the scale of that little bowl when you held it with the clamps. Looks tiny.
On the first part was the middle part not freezing because it had a higher freezing point than the other liquids. Or is it because it is in the middle and the cold can't reach as much there.
