Coke can piggy bank

This is a simple can lid that changes an empty can into a simple piggy bank.
First you have to file the top of the can, as seen on the second picture (easier and cleaner than using a can opener).
Then you glue your new lid with epoxy and you're done. A cheap sealed piggy bank you'll have to destroy to get to the precious innards !

This is a prototype, some changes might happen in the future.
