Some piggy banks are broken to take out coins, so when the piggy bank is broken, can it be as perfect as fireworks? For the material of this piggy bank, I chose various colors of clay, sand and other materials, so that when the piggy bank is broken, it will have a similar effect to colorful fireworks. Smashing the piggy bank is like setting off a firework. The act of withdrawing money is explained in a different way. At this time, the piggy bank is sublimated after it has completed its mission.
