This a very simple Instructable I thought up last night. Reusing and creating a piggy bank out of an empty Powerade bottle.

You don't need to use a Powerade bottle, anything with a lid large enough to fit a quarter is good enough, this is just what I had on me at the time.

Step 1: Materials and Creation

The materials needed are:

1) Empty (Powerade) Bottle with lid
2) Dremel

That's all!

What you do is trace a rectangular box on the lid of the bottle, and use your dremel to cut it out.
Sand the inside of the cut if you like.
