What You Did
You built a parachute for small toys.
Your toy should gently glide down to the ground rather than falling fast.
This experiment worked for me the first time, but there are a lot of strings to tie to the object. I realized while tying them, it could cause a problem if you tied them on one at a time. I gathered mine up together and made one knot, which kept all the strings the same distance from toy to parachute.
Try out different parachute shapes and sizes. Send different sized and weighted toys out for a jump
