Ever played with a Slinky? It was my favorite ‘fidget’ from back in the days. Giving it a new lease of life is this Elongation Piggy bank by ShaoJun Zhang. We can call it a whimsical expression of design, because there is no practical affluence when it comes to getting the savings out of the piggy bank. You simply open up the spring and let all the cash tumble out of the seams… literally. Use the slot on the top to pour it all back in!
