Want to save money but keep forgetting to deposit cash to your piggy bank? Consider buying yourself the new Exploding piggy bank by Tomy CO Ltd. This innovative piggy bank shakes, shines, and even ‘explodes’ to remind you to feed it daily. If you do not deposit money every day it reminds you on an hourly basis by vibrating and making noises. If it fails to get your attention it finally ‘explodes’, spilling all your savings. Alas, this piggy bank will only be available in Japan from next week.
