Would an egg roll back to its original spot if you tip it? NO.
But how can we change that?
Step 1: Supplies
All you need is:
plastic Easter egg
Step 2: Taping
Tape the penny to the bottom of the egg (where you want it to be standing on) with tape. Then close it.
Step 3: Testing
Tip the egg with your finger and see where it sits. (back up to it's original position)
