If you were really making up a bunch of Aerogel, you would be a millionaire. This stuff is not Aerogel. Hold a blowtorch up to it. I dare you!

[pimbilibom]

You are right, this is sol-gel, aerogel is made of it by supercritical drying.

Esta reacción es conocida desde 1640 como el silicato de sodio condensación. Aerogel proceso se inicia el mismo que el gel de sílice, salvo el proceso de secado es diferente, principalmente.

[pimbilibom]

Para hacer esto en casa, tomar el vinagre y el silicato de sodio. Diluir con agua a 1:1. Tome cantidades iguales de ambas soluciones. Ácido revolviendo constantemente. Goteo de silicato añadir. Filtrado. Forma de gel en cuestión de minutos a varias horas dependiendo de los coeficientes de concentración.

Aerogel is born in liquid (step 1). Later it is dried supercritically.

After that any liquid will destroy it.

o_O Wait, aerogel in water? Why is it not absorbing the water, like another video I saw on here? Turned all misty like ice and, according to the video poster, was ruined.

*is absolutely fascinated by this stuff @___@*
