Tennis Ball Mortar

Step 2 Building the mortar tube

Step 1: Eat the chips. Vomit when necessary. Repeat. (I was making a joke about the flavor of the chips, but it also works nicely as a beginners guide to bulimia)

Step 2: Wash out the cans with soap and warm water. Do not get the cans too wet or the cardboard will lose some of its integrity. Dry cans.

Step 3: Cut out a circle in the center of two of the cans metal bottoms. The diameter of the hole should be equal to the radius of the metal bottom.

Step 4: Stack the two cans with baffles (holes) on top of the solid bottomed one, and duct tape heavily ( 7 - 12 times around) at the seams.

Step 5: Completely cover the cans in duct tape at least three times (three layers of duct tape thick)

Step 6: Poke a 1/4" hole 1" from the bottom of the mortar

No, you should leave about 1/4" on each side of the hole.

Hey, how many cans of pringles are supposed to have the circle in the bottom?
And which ones?

Hahaha love the bulimia joke. Very tasteful. =] Also, try using this as an over-the-shoulder rocket launcher? =]

What would suck if the tennis ball somehow got jammed in there and the whole thing exploded next to YOUR FACE.
