Forget stress balls and punching bags. If you're feeling destructive and simply want to break something, check out the Anger Release Machine.
Created by artists Katja Kublitz and Ronnie Yarisal, Anger Release is basically a traditional vending machine stuffed full of glassware and china. When someone pays money for a particular product (say, the beautiful vase at D4, or the porcelain cat at C3), the coils slowly push the fragile piece to the front. And then it drops just like a bag of potato chips would ... except with a slightly noisier crash!
