What is in a gel sac? Would it be any good at sound proofing?
So yeah, I was thinking about making a sound-proof box as part of a project and wondered: would a gel sac make good sound insulating material. You know the stuff I mean - the little sac like things you can't help but prod about on posh mouse mats and on gel bike saddles.
Thinking about that I also realised I didn't really know what the 'gel' material actually is? Is it possible to easily make a similar or substitute substance at home? Thanks.
