Last week,our class did an experiment about air pressure. It was making a toy parachute. We were asked to bring :
-a small toy
-a big plastic bag
-string
-scissors
How to make it was not really hard :
1. make a cone shape of one side of the plastic bag and cut it, it will shape like a circle
2. make at least 8 holes on the end of the circle
3. cut the string and tie it on the end of every hole
4. tie the toy on the strings
5. decorate if you want
after making, it's time to throw the parachute from the heights :P
It was a fun experiment, I hope we can do more in the future !
