Hello everyone, this is my first instructable and I hope that this is helpful and fun for you.

Behold.....

The giant potato launcher. It can launch potatoes up to 240 feet away and 30-90 feet high. The greatest thing about this is that you can build it for under 30 dollars.

Supplies

4 2x4 (8ft long)

2 hook screws

4 bungee cords (48 inches)

Screws (any size)

4 Wheels (optional)

Square metal pipes (2 pipes that are 3ft long, and 2 pipes that are 2 1/2 ft long)

piece of leather or fake leather

Step 1: Cut the 2x4 to Size

Cut 2 of the 2x4s. The 2x4s should be 8 ft long. Cut the 2x4s so that they are split and 1 part is 2 ft long and the other part is 6 ft long. Then cut a piece that is 2 ft and 3 inches long from the 3rd 2x4. Any saw is fine, but I am using a hacksaw because that is what I have, but you can use electric tools or just hand tools to do this step. Cut the last 2x4 in half so that each side is 4 ft long

Step 2: Build the Base

After you cut the 2x4s to size, then drill the holes on the 2 ft long 2x4s (in the photo) and then, do the same drilling in the long pieces (6 ft long), at the end of the wood. Lastly, add the screws at the end and it should look like the image above.

Step 3: Set Up the Post

Get the 4 ft long 2x4s and add them on vertically. I used nails to set the piece of wood in place but you can use screws if you want. I just added a big screw in the middle to keep it sturdy.

Step 4: Add the Trusts

After step 3, the post was not as sturdy and rigid as I wished it would be so I added trusts. I found some spare square tubing and I drilled holes in them and screwed them to the pieces of wood that went 90 degrees up and the base, so now, we are almost done.
