HOW TO MAKE A COIN FLOAT ON WATER??

Can you make a coin float on water? You can't? Then try this experiment!


Materials:
A coin
A glass of water
Cup
Blu tack
A non transparent china or a plastic cup


Instructions

Place the blu tack in the middle of the coin and place the blu tacked coin in the middle of the cup.


Position the coin so that it would not move when water is poured.
Pour little water (do not fill in the cup)


Now move back until you cannot see the coin inside the cup anymore and pour some water from where you are standing. AND VOILA!! The coin magically rises!!

This is just an optical illusion! The coin does not actually floats up!
