BALANCING BOTTLES

You will place a crisp hundred rupees note on the rim of a coke bottle, and another bottle of the same size is set upside down on top, so that one bottle is balanced precariously on the other, with the hundred rupee note in between.

CAN YOU TAKE OUT THE NOTE WITHOUT TOUCHING THE BOTTLES?

With a quick, deft move, you can take away the note, leaving the bottles still balanced. It's simple science!

YOU WILL NEED:
Two empty soda bottles.
A crisp note. Play money, or a sheet of paper cut to size can be used instead of the note.

INSTRUCTIONS:
Balance the bottles very carefully by holding the note with your
other hand, keeping the note toward one end, rather than centering it between the bottle rims. Draw the note with one hand, then extend the forefinger of the other hand and hit the note near the center, with a quick, hard downward stroke. The note will whip
away, leaving the,bottles balanced.

SCIENCE BEHIND:
This is a classic case of inertia as explained by Newton in his first law of motion. The slightest impulse given to the upper bottle would cause it to topple and fall, but due to its weight, the
removal of the paper is trifling and therefore has no perceptible effect upon the balanced bottle.

You use the same law to prevent yourself from accidents by putting the seat belts while driving.
