Build your mechanical piggy bank step by step. It reacts to an inserted coin with motion and a satisfying “click.” This simple project supports logical thinking, dexterity, and naturally introduces kids to the fundamentals of mechanics.
An easy-to-follow manual is included, so even beginners can assemble it. Once finished, you can “feed” the bank with coins and experiment with different objects—watch how the mechanism responds and discover why it behaves that way.
