Sound can have some amazing effects on liquids - and some downright bizarre effects on non-newtonian fluids such as the conveniently simple mixture of cornstarch & water. I'd experimented a bit with cornstarch cymatics in the past, but never quite matched the writhing results I'd seen from others. Now, after bringing my own small puddle of goop to 'life', I feel pretty much satisfied =]

Hello,
Just looking at how you built it, is it required to remove the cone in the middle? Just wondering what effect that has?
Also, this removing of the cone, is is required to do in all cymatic builds? For this, im referring to the make your own rig on this website as it doesn't say on there if the cone needs to be removed.
Thanks
