There
are lots of ways to make a parachute:
#1
- Cut a
circle of plastic about 30 inches in diameter.
I used a large garbage bag which I cut open and
then I used the lid from a round trash can as a
guide to cut the plastic into a circle.
- Punch
8 holes around the edge of the plastic circle.
To make the parachute stronger, first put some scotch
tape on the plastic where you plan to punch the
holes.
- Tie 18
inch pieces of string to the plastic circle.
Try and make each piece the same length. Tie all
eight pieces together where the cargo hold will
be attached.
- I used
a piece of sponge for the cargo hold.
Cut a little hollow in the sponge so that the egg
can balance in it.
- Now go
and test it out !!
(You may also need some cleaning materials to wipe
up any mess)
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.
#2
- Cut a
cellophane or tissue paper square (36cm)
- Put a
piece of tape on each corner
- Punch
a hole through tape at each corner
- Cut four
pieces of string 41cm long
- Tie a
piece of string to each corner
- Tie loose
ends of string together
- Attach
paper clip (add more to increase the load)
