Things You'll Need
Instructions
Cut the handles off of a plastic grocery store bag with scissors, but leave about one inch of each handle attached to the bag.
Tie the end of a 2-foot string to the stump left from one of the handles, then tie the other end of the string to the stump of the handle diagonally across from it.
Tie a second string to the remaining two stumps.
Hold the bag at its center at the top of the chute so the strings droop toward the ground. Thread an 8-inch string through the loops formed by the hanging strings, then tie the 8-inch string so it secures the drooping strings together at their lowest point. Use the tag ends of this string to attach a payload to the parachute.
