Scientists are taking aim at the physics of rubber band bombardments.
Using high-speed video, researchers have analyzed what happens to a rubber band when it’s launched from a thumb.
The results offer some tips for how to make a clean shot, Boston University mechanical engineers Alexandros Oratis and James Bird report in a paper in press in Physical Review Letters.The researchers focused on one particular shooting technique: Elastic is slung around the raised thumb of one hand and pulled back with the fingers of the other hand. Standardizing the operation by using a cylinder rather than a thumb, the scientists filmed the details of the shooting process.
When the rubber band is let…
