Aerogel (Patreon)

First attempt to make aerogel. I somehow ran out of liquid CO2 right before the supercritical step, so it had to be done way too quickly and with too little co2. This caused a lot of cracking, but it did work. Over the next few weeks, I'm going to make a few more. With a fresh co2 tank I should be able to make one that is almost crack free.
