Place the little red ball on top of the blue vase. Cover it with the blue cap, and quickly remove the blue cap to reveal the red ball is nowhere to be fund! Just as quickly, as soon as you put the cap on the vase and take it off again, the red ball amazingly is back on the vase! Take the ball out of the vase, put the ball in your pocket, put the cap on the vase, lift the cap off- the ball has invisibly returned to the vase!
This is very easy to perform, kids ! And you can repeat it immediately. If you are able to put the cap on the vase, you are able to do the trick!
