Scientists crack the case of 'screeching' Scotch tape

Researchers have discovered that the screeching sound produced when peeling Scotch tape is due to micro-cracks that travel along the tape at supersonic speeds. These micro-cracks generate shock waves and sound pulses, explaining the phenomenon that has puzzled many. This finding not only sheds light on the acoustic properties of adhesive materials but also has potential implications for understanding similar behaviors in other materials. The study highlights the intricate physics involved in everyday actions, such as using tape, and opens up avenues for further research into material science and acoustics.
