Introduction: Tennis Ball Squirtgun

A quick mod for a tennis ball. Can be used for a variety of purposes including: squirtgun, water bottle, ammunition, and more!

Step 1: Materials

Tennis ball (duh)
Exacto knife, or any other sharp object

Step 2: Stab It!

stab your tennis ball (just once) with the sharp object. I found it was much easier to stab on the rubber lines, instead of messing about with all the fluff.

Step 3: Fill 'er Up

When you squeeze the tennis ball on either side of the crack, a hole will appear. hold this under a faucet and squeeze it a couple times to suck in water.

Step 4: Squirt

To make the tennis ball squirt, squeeze it! the water will come out in a jet about 10 feet long ( if you squeeze it hard enough). the picture doesn't do the gun justice.

Other Ideas:

1) emergency water bottle
2) pranks >:)
3) flamethrower? (NOT A GOOD IDEA, I don't suggest you fill it up with kerosene)
4) weighted ammunition for something (ex. The Easysling)

    You gave me an Idea. It would be hard but imagine, taking a card board box and filling it with newspaper. Light it on fire and throw a oil or kerosene filled water balloon an watch it catch aflame!

    Now you have given me an idea..... what happens when you light a paper airplane on fire?

    I did that once. I drenched it in lighter fluid and threw it and it was a mini 9/11.

    That wasn't funny. Not at all.

    You should of posted that comment the day before.
