The gadget is a resin jug designed to fit over the contours of your mouth and absorb your screams, shouts and frustrations. It releases a whisper soft version of your anger, which comes through the tiny hole at the base. Don’t let it dwell inside, shout it out without disturbing your neighbor.
Positively the best gift for anyone with a stressful job, home, or just for a loud one in the family. Every office should have this shouting vase to release the anger and keep the peace. (see here)
