Updated aerogel link

Amazing video! Loved watching every minute of it. I may have an idea as to the yellow coloring in the hexagonal piece of aerogel. If you pause the video exactly at 33:35, you'll notice that the teflon tape towards the end of the thread is a lot darker than the tape closer to the glass. I bet the color from that tape leached into the liquid CO2 during your second run with the hexagonal piece.

About the Sous-vide cooker. You probably would have gotten away with a fish tank heater. They're only $20.

Sodium Silicate is non soluble in alcohol. But I'm told it forms a gel, when mixed with Ethanol. Apparently you can make good boiling chips this way.

Keith Emery

Perhaps just dissolve Sodium Silicate in Anhydrous Ethanol / Methanol, and allow the Silica to form as the Supercritical CO2 replaces the solvent? It might remove at least one step?

Keith Emery

If Sodium Silicate forms Silicon Dioxide on contact with CO2. Is there a way to expose Sodium Silicate to supercritical CO2 in a direct fashion?

Awesome video! I’m looking forward to you’re upcoming work this year

Oh, sweet, thanks!

I updated the link with you in the credits :)

I watched this video before bed yesterday, and it was fantastic! I don't really have anything I'd like to comment on, other than that I was really excited about this video and it was fantastic and very satisfying. Totally glad I'm a patreon

I actually don't think it has changed too much. I think it's just organized differently now.

Nile Red

hey, I'm really sorry about that! I have to do it all manually and I sometimes miss names :(. I will definitely fix it for next time and I will actually try to fix it for this time. I might be able to render it and upload it in time

I upped my donation to $10 a while ago and I’m still in the $5 credits — I didn’t care enough to say anything previously but maybe others are in the same boat, and the count of supporters might look skewed. But I’m only donating because this is amazing stuff that I can’t get enough of 🙂

if you ever try making it again, you can try to mold it the way gummy candy is made. They have a bed of starch and press shapes into it, then pour in the candy. The removal from the mould should be very easy

There are two types of science videos I'm personally interested in: big (costly) journeys where someone like your tries to reach a goal. The other ones are videos that give me useful(!) knowledge and teach me methods I absolutely could do myself. Of course my Interest is sparked by the fact that I COULD do it myself even when I know that I won't do it myself. Price, toxiticy and availability (in Europe where I live) are key: "make your own plastic only by shooting pure gold out of an AK47 into Cyanide" does not tingle my DIY spirits... I would watch it though. :)

Could the old link be made un-private after the full public release? So patrons have access to the ad-free version?

We've lost a few $10 tier supporters. I can tell, because my name is now at the top of the list, that's not good news. Great video none the less.
