Make a homemade parachute out of a plastic grocery bag! … Parachutes work because air resistance pushes against the surface material, slowing it down. You can make your parachute fall straighter by cutting a small hole in the middle of the plastic bag to allow air to flow through the middle rather than over the sides!

This gives a slow fall and a soft landing.
