What goes down... might send something back up...
If you've ever done a jackknife dive into a pool to see how high your splash could go, you'll know the general idea of the "cold backfire."
I did this one in a couple hours... the audio was ENORMOUS fun to do! Anyone want to take a stab at how I got the "ploop" sound? (=
On a side note: I'm doing a series of VLOG/Production Diaries on the making of my next short so check those out if you're into behind the scenes stuff like that!
