|Jenga is a game of physical and mental skill, in which players remove blocks from a tower and put them on top. Matthias Wandel has made a wooden Pistol for Jenga. Called the Jenga Pistol. The Jenga Pistol is able to shoot Jenga blocks out from the Jenga tower so quickly that the layer of blocks on top fall down and do not cause the tower to fall. (watch the video!)
"The pistol works by hurling a wooden captive bolt forward inside the pistol, powered by rubber bands. The bolt has a pin on the front, which protrudes out of the muzzle of the gun by about 2 cm at most. This is enough to transfer the momentum of the bolt to the Jenga block in front of the gun, not unlike how the game of croquet works. "
