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
1) Measure yourself from the floor to shoulder height.
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
cut a rectangular piece of cloth 10 inches by 7 inches from your scrap T-shirt.
(25.4 cm by 17.78 cm)
Step 4: Reinforcements!
Tape duct tape on all four corner to reinforce the areas where you will be putting your rope through.
(duct tape only needs to be on on side)
Step 5: Make Holes!
Make Holes in all four corners through the duct tape and cloth.
I just stabbed it with my scissors, but you may want to do this differently.
Step 6: Feed Rope Through
Flip your cloth over, then feed your rope through one hole and out the other.
(do this on both sides of the cloth)
Step 7: Tie Some Knots
Even out the ends of your rope and tie a simple overhand knot with the two.
Do this with both ropes.
Step 8: TADA!
finished with the sling
Step 9: Holding the Sling
take your dominant hand, and feed one of the knots between your middle and pointer finger. bring the knot over to your pinky and hold the knot loosely there. bring the other knot between your pointer and your thumb, and pinch it there. Now, clasp your hand into a fist.
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)
