These are the the wrist-mounted cannons that harmlessly blast mini-marshmallows up to 30'. Two cannons are included, providing an ideal sibling deterrent or enforcer of playhouse détente. It straps to a wrist using a hook-and-loop fastener; a few squeezes of its air-pump handle builds pressure and a press of its forefinger trigger launches a marshmallow. Up to seven mini-marshmallows fit in the cannon's transparent, dishwasher-safe loading tube and each "round" automatically drops into the launch chamber. Ages 6 and up. Set of Two. 8" L x 4 1/2" W x 6" H. (9 oz.)
