DIY Nerf H.A.M.P.

Here is a video I made showing you how to make a H.A.M.P. (High Air pressure Manual Pump) out of PVC. This gun will shoot Nerf darts, slugs, and stefans up to 100 feet. This is a great gun to use at Nerf wars or just in your back yard shooting targets.

Step 1: The Materials You Will Need

A length of yarn

Duct tape

Cutting too ( in my case I used a coping saw)

You will need to cut a 3" piece from the 2" PVC to connect the elbows together.

2" PVC (The length is up to you I chose to cut a 2ft in piece)

1" PVC (The length is up to you I chose to cut a 1ft 10-1/2 in piece)

Two 2" elbows

1/2" PVC (The length is up to you I chose to cut a 1ft 10in piece)

Reducers/PVC Bushings:

2" to 1-1/2"
