When a person stands against a wall, touching it with the right or left portion of his body, he cannot raise his own leg.
Necessary materials:
A wall with the surface even
Method:
Call one of the viewers and ask him to stand straight against the wall sticking the complete right or left portion (except the head) of his body. Then pronouncing the magic spell, whirl the magic-stick around his body, and touch his right leg twice with the magic stick pretending to beat. Now ask him to raise his right leg. He will not be able to raise the leg in spite of trying his best.
The Scientific Reason:
This too happens due to the very C.G.. Since one side (half portion) of the body is free, it is difficult for the C.G. to change its position. Consequently the leg cannot be up lifted.
Precautions:
The right or the left portion of the body (from leg to the arms) should be well stuck to the wall.
Practise for once or twice before the demonstration.
