It is exactly what you think it is, a sushi making tool that works like a cake frosting bag. You put your fillings in the middle and the rice on the outer chamber, close it up and push the (Sushezi) Sushi Bazooka's handle. Now you have what looks like a roll of rice, wrap that in seaweed and cut it into slices. Genius. Video of the Sushezi Sushi Bazooka after the break.
