This activity is both a science experiment as well as a puzzle. You will need two plastic glasses, two balls, a pencil and some rubber glue. Place the two balls in one glass and then apply rubber glue to the entire rim of the glass. Now stick the glasses together by placing the second glass on top of the first one. Press the rims of the two glasses and let the glue stick them tightly. 
Now if you were asked to separate the two balls – put one ball in each glass, this would seem tough. But just place the glasses on a table and spin them! The balls will be separated. The spinning glasses will make the balls fly towards the extreme ends. 
Fix a pencil in the middle. The pencil stem will enable you to spin the glasses better. 
You can also spin the pencil between your two palms. The glasses will spin and the balls will fly to the bottom of the glasses because of centrifugal force.
