Tattoo a banana

Got a banana?  Got a safety pin?  Great.  

Now you can tattoo a banana.

 Materials:
- banana
- safety pin
- pencil
- refrigerator

Directions: 
1.  Use a pencil to sketch a design on a banana.  (If you don't feel comfortable sketching straight on the banana, you can sketch your design on a piece of paper first.  Then, tape your design to the banana to guide your poking.)

2.  Use your safety pin to poke holes in the banana.  Watch your tiny dots turn black.

3.  Place the banana in the fridge for a couple of hours.  Pull it out to reveal a new tattooed banana.

4.  Place the banana in your kid's lunch box.... or sneak it back into the pile of bananas at the grocery store to surprise shoppers.

Happy tattooing!

(I first spotted this idea on the excellent How About Orange blog.)
