For people with a penchant to physics or engineering, taking a shower is not only a cleaning procedure. Have you ever asked yourself why sometimes you spill water droplets all over the place whereas at other instances the water just flows down the walls? Well, droplet physics or engineering will provide you with an answer. The speed of the water and droplet beam, the size and angles and, maybe, the kind of soap or lotion you apply have a decisive impact. If you have sufficiently investigated this question, you can turn to the acoustics of droplets falling down and the rebound on the floor. We do not know, whether Jean Sibelius, the Finnish composer did such studies in his shower or Finnish sauna before he composed his water droplet duo. We can only encourage to take water and liquids more seriously in our daily lives. (Image and Instructions for experiments under Rainfall Shower)
