UPDATE: NEW VIDEO FEATURING SAFETY EQUIPMENT
Step 1: Gather your materials and tools!
1) Old T-shirt
2) rope (about 20 feet)
3) Duct tape
Step 2: Measure yourself
2) Take that number and double it.
3) cut two lengths of rope that are your shoulder height doubled.
Example: I am five feet from the floor to my shoulders, so I will double that. I end up with 10 feet, so I will cut two lengths of rope 10 feet long
Step 3: Cut T-shirt
(25.4 cm by 17.78 cm)
Step 4: Reinforcements!
(duct tape only needs to be on on side)
Step 5: Make holes!
I just stabbed it with my scissors, but you may want to do this differently.
Step 6: Feed rope through
(do this on both sides of the cloth)
Step 7: Tie some knots
Do this with both ropes.
Step 9: Holding the sling
Step 10: Sling stuff!
The object will have to have some weight to make it possible to spin the sling around your head. once you are holding the ends of the ropes, and you have your projectile in the pouch, check your surroundings. Make sure there is no one around you, even behind you. If you release at the wrong time, your projectile could go flying anywhere! Start to spin the sling around your head. Release the knot that is in between your pointer and your thumb when you feel your timing is right. When done correctly, your projectile will fly very, very, far! (I have gotten a water balloon to fly about 100 yards)
