Not all science awards are reserved for discoveries that revolutionize their fields. As the Ig Nobel Prize recognizes, sometimes a largely pointless, but wildly creative, study is just as worthy of accolades. On September 13, the Ig Nobel Prize continued its tradition of honoring achievements "that make people laugh, and then think" with its 28th annual ceremony.
The Ig Nobel Prize recognizes work across a variety of fields. This year, the medicine prize was awarded to Marc Mitchell and David Wartinger for their investigation of whether or not riding a roller coaster can dislodge a kidney stone. The answer: It can, at least if you're riding in the back car of the Big Thunder Mountain coaster at Walt Disney World. Other notable winners include a study detailing a self-administered colonoscopy and one that asks if using a voodoo doll of your boss is an effective way to manage workplace aggression (it is).
