Sure...here'smy step by step guide:

1) Head over to the "furniture" and grab two of the "easy to assemble" night stands. Once assembled place them 28"(26" for woodies)apart. Lay the arrow shaft across the nightstands.

2) Go to the bike section and confiscate the pressure gauge of a tire pump. Attach to one of the nightstands with wood screws from "hardware"

3) Go over to sporting goods and pick up one of those littleone pound dumbells for women (No I don't mean the idiot teenagerbehind the counter selling them either)

4) Grab a Flower pot hanger from "home & garden"

5) Attach the dumbell to the the flower pot hanger.

6) place the hanger on the center of the arrow shaft

7) get a reading from the tirepump guage

If you actually get a reading, you've done something wrong
