Magician displays an aluminum tube about 10″ in length & a small brass block which fits into the tube. A spectator holds the tube vertically and drops the block into the top and then catches it at the bottom of the tube with the same hand. The block falls in less than 1 second. The magician explains he will make it easier by removing gravity’s pull inside the tube. This time, the block can be seen floating slowly thru the tube! Magician restores gravity, block is dropped again & it shoots thru the tube quickly!
