Piggy banks are a fun and exciting way to teach your children how to save money. While many piggy banks today are made from plastic, some newer and antique versions are made from ceramic material. Ceramic piggy banks are typically more expensive than their plastic counterparts and have the potential to become collector items. When it comes time to "break the bank," or extract coins from your piggy bank, care must be used to avoid possible injury from ceramic shards.
Insert a butter knife into the opening of the piggy bank and hold the bank upside down while you jiggle it to remove the coins. The butter knife will act as a ramp for the coins to slide out of the piggy bank. Using this method of coin retrieval will best serve people who have a piggy bank without a rubber or plastic plug installed on the bottom of the bank and wish to keep the bank intact.
Check the bottom of your piggy bank for a rubber or plastic plug. Use your fingers or the butter knife to pry underneath the plug and pop it out to retrieve the coins inside the piggy bank.
Wrap the piggy bank in a thick towel completely and place the bank on a hard surface such as a kitchen table. Strike the top of the piggy bank once with a hammer. Unwrap the towel from the piggy bank and carefully remove the shards and throw them away, leaving only the change in the towel.
