Intro: Super Strong Vice-Grip Catapult

This is easy to build and requires very little work.

I've been able to launch rocks as high as 30 feet!

(I was going to show the final result but it was very hard to see the rock.)

How-To Video▼

Step 1: Parts

Materals:

1 Vice-Grip

1 Cable-Tie

1 Piece of Wood

1 Bottle cap

1 U-Bracket

2 Screws

Tools:

Drill

Chisel

Pencil

Utility Knife

Mallet

Step 2:

Cut two slits the size of the cable-tie.

Feed the cable-tie through the top of the cap then through the second hole.

Step 3:

Place the wrench on the board and make a mark where the front of the wrench touches the board. (Make sure you leave room for the adjustment screw.)

Then chisel a notch to hold the wrench stable.

Step 4:

Screw the the wrench in place with the U-bracket.

Step 5:

Finish by tightening the cable-tie around the wrench handle.

Step 6:

The more you tighten the adjustment screw the stronger the catapult is.

You're done!

Now take it outside and have some fun!

    sounds a bit dangerous to be flinging rocks 30 ft into the air.
