I think the Screambody is one of the most practical crazy inventions I’ve seen so far.
I always have this problem- something happens, I get annoyed or pissed off or something, and I feel like I need to scream my rage out. But scream? Can’t really do that.
Currently only a prototype, the Screambody is a “wearable body organ,” that lets you scream at full volume without being heard (it even records the screams, in case you want to play them back later). Basically, a way to get the screams out of your system.
