Let’s Make a DIY Parachute!
Making a Parachute is a fun craft project and also an educational science experiment that can be done at home. So let us begin and make this homestay fun and productive.
- Plastic (polythene)
- Load (small nut)
What to do next?
You can follow these simple steps to make your DIY Parachute.
Take a plastic bag.
Fold it in half.
Cut the two ends of the plastic bag.
Unfold the plastic bag
Cut off the edges so it looks like this
Turn the plastic sideways and fold the corner to edge
Cut the bottom part to make a square.
Fold the plastic bag in the shape of triangle four times.
Fold it again and it will look something like this.
Cut the bottom part making an arc.
Completely unfold the plastic bag.
Draw a diameter and mark dots at 60 degree around the circumference of the plastic bag. Make small holes on the dots as shown.
Take a piece of string and make its length three times the radius of the circle.
Tie the string on one hole of the circumference of the plastic bag.
Take five more strings of the same length and tie them on the remaining holes.
Place a small object at the end of the string and it is ready for testing
Try the same activity using different material like newspaper, tissue paper, napkins.

- What changes could you make to improve your design?
NOW TIME FOR SOME SCIENCE
When a coin is dropped from a height, it will reach the ground within a very short period of time. It is because the air resistance (a force acting opposite to the direction of the coin) is very small due to the smaller surface area of the coin. While, when the parachute is dropped from a certain height, the envelope of the parachute(plastic in this case) increases the surface area resulting inaction of more air resistance. Thus helping to slow down its speed.
