A yellow can with black spots tube is shown empty. The container has no top or bottom and the audience can clearly see all the way through the tube. The magician  drops a ping-pong ball into the tube but it doesn’t fall out. The magician explains that this is due to “heavy air.” At his command however, the ball falls out the bottom of the tube. Rope, a magic wand, or other small object can be dropped into the tube with the same result! This is a fun and easy to perform effect. The trick has been discontinued by the manufacturer and we have two left in stock. 001CBMHEAVYAIRTUBE
