Release the aerodynamic force, let the stack to a new height!
Put the ball at the air outlet of the base, insert a section of transparent tube and turn on the fan, then the ball will climb to the nozzle and keep suspended, isn't it amazing? The ball will drop to the bottom of the pipe immediately after capping any pipe orifice, the cool design of simulating rocket launch, and the cute animal decorative sleeve includes three cartoon image sleeves, four transparent sleeves, two balls and fan base. The fan base provides air upward to push the ball to climb the sleeve.
