So here’s Elastic Reality, unicorn mare of unusual scientific pursuits. As a filly she was always fascinated with the bizarre, unexplainable anomalies of physics in the world she lived in. Sometimes, ponies could do seemingly impossible acts with their bodies, like getting smashed flat behind a door, or blown up like a balloon when they needed help breathing. She believed there must have been some kind of rhyme or reason to these acts, and began studying their properties, conducting many… questionable experiments on those around her (as well as herself, when she couldn’t find any volunteers).
