4m green science magic water tap kitBuild this stunning water tap that magically makes a non stop stream of water. It pumps out water like a normal tap but it seems to float in mid air! Your friends and family will be amazed! Place the tap next to a fish tank or against a wall to create a fascinating illusion! Add an art template to the water tap (like the rocket provided) to make a fun decoration. The illusion of levitation is created by using a chain that's too short to reach the tap,
