Deodorant's great for killing obscene body odors, but it's not so great for personal expression. Change things up by exchanging your roommate's deodorant for their favorite color spray paint. Armpits have never been so colorful!

You Will Need:

Almost empty spray deodorant

Spray paint

Pen

Instructions:

1. Take off the deodorant top so the nozzle is exposed.

2. Take off the spray paint top so its nozzle is exposed.

3. Take apart the pen completely until you find the inner pen tube.

4. Attach the inner pen tube to the top of the deodorant nozzle and make sure it fits tightly.

5. Place the spray paint upside down and attach it to the other end of the pen tube.

6. Press down hard and make sure both nozzles depress.

7. Clean off any paint spillage on the deodorant bottle and place it back where it belongs.

While this prank works with any color spray paint, it's best if you go for bright neon. That way when your roommate comes chasing after you, you'll be able to spot his armpits from a mile away, and will be able to get a good head start.
