What are the two essential holiday accessories (apart from lounge chair and bath)? Answer: Frisbee and . Unfortunately, one doesn’t replace the other, as a new study has just shown that it investigated whether cardboard coasters can make a good Frisbee. To do this, researchers (naturalistic German) from the Helmholtz Institute for Radiophysics and Nuclear Physics and the Institute of Astronomy at the University of Bonn built a ship throwing device and conducted a series of experiments designed to study These mini cardboard discs are 10 cm in diameter.
The beer coaster has been inverted making it unusable as a flying saucer
« You might expect the beer ship to fly the same way a frisbee does, with angular momentum pointing up or down causing the disc to stabilize., the researchers write in their study published in . Unfortunately, given the relatively low mass of the cardboard, the ship undergoes chaotic rotations around the axes of the disk. In addition, unlike Frisbee which has rounded edges and a coil Near its center – preventing its capsizing early – the beer vessel undergoes its lift adjustment, not in the center of the disc, but slightly offset from the leading edge. ” This calls for the extension making it unusable as a Flying Layer ‘, the authors testify.
Barely 0.45 seconds of stability
The researchers confirmed the result…
