When an object falls from a great height it picks up speed, but the resistance of air finally causes it to fall at a steady speed. The large surface of a parachute acts as an air brake, checking the velocity of the person or object attached and making it possible for a safe landing. You can make a parachute.

You will need:
  • Handkerchief
  • Some string
  • Small ball or a small doll
How to make a parachute:
  1. Tie about ten inches of string to each corner of the handkerchief
  2. Fasten each piece of string to the ball or the doll
  3. Toss the parachute into the air or drop from the top of the stairs
