Use Science and do magic on plastic glass

 Hello

Today I want to tell you a science experiment trick that becomes you a magician.

Thing's required

i) A plastic glass and peace of plastic perfect round shape cover

ii) A small piece of cardboard (large than the surface of the glass)

iii) A pin ( able to make a hole on plastic glass)

iv) Half glass of water

Experiment/ Trick

1) You take the plastic glass and put water in that glass.

2) Cover the end of the glass with that round shape cover & cardboard and turn the glass.

3) Make a small hole in the glass and a little beat press the glass.

4) Then Close that small hole and without moving glass take the cardboard.

You see that water is not falling down. 

Because it creates a vacuum.

When the glass is press then some air goes out from the glass and we close the hole then vacuum is created then the water is not falling down. 

I hope this makes you interesting in and knowledgeable about science experiments/tricks.
