What you'll
need:
1. A plastic bag or light
material
2. Scissors
3. String
4. A small object to act as the
weight, a little action figure would be perfect.
Instructions:
1. Cut out a large square from
your plastic bag or material.
2. Trim the edges so it looks
like an octagon (an eight sided shape).
3. Cut a small whole near the
edge of each side.
4. Attach 8 pieces of string of
the same length to each of the holes.
5. Tie the pieces of string to
the object you are using as a weight.
6. Use a chair or find a high
spot to drop your parachute and test how well it worked, remember that you want
it to drop as slow as possible.
What's
happening?
Hopefully
your parachute will descend slowly to the ground, giving your weight a
comfortable landing. When you release the parachute the weight pulls down on
the strings and opens up a large surface area of material that uses air
resistance to slow it down. The larger the surface area the more air resistance
and the slower the parachute will drop. Cutting a small hole in the middle of
the parachute will allow air to slowly pass through it rather than spilling out
over one side, this should help the parachute fall straighter.
