19 Jul Physical description and modelling of paper strip flights
When a confetti cannon is fired, a turbulent spectacle follows: hundreds and hundreds of paper snippets swirl through the air in fantastic trajectories. It is this phenomenon that Leonard Münchenbach and Leo Neff devoted themselves to with scholarly rigour in their research project. They constructed a frame that made small strips of paper fall to the floor in the same way each time. A slow-motion camera was used to film the action and computer software helped analyse the footage. The young researchers investigated a wide variety of strip shapes – some long and narrow, others short and wide. Among other things, their findings enabled them to arrive at a formula that can be used to precisely calculate how fast paper strips of a certain shape and size rotate when they fall.
