A simple faucet, using physics The construction of a simple faucet in the countryside using air pressure in a bottle. Water flows out of the yellow straw if the pressure in the bottle is greater than atmospheric pressure. By moving the blue straw up, we reduce the pressure on the end of it and air leaks through it. Because there is a leak, the air gap is reduced under the lid and the water flows out. By moving the blue straw down, we increase the pressure at its lower end due to the water column and the water stops flowing.
Guitar with swivel neck Musician Charles Berthoud plays an electric bass guitar with a swivel neck created by YouTuber and engineer Mattias Krantz. Krantz got the idea to create this funny guitar while watching a Beatles documentary where Magic Alex (Alexis Mardas) gave John Lennon a double-sided neck guitar (electric and bass). Unfortunately, the guitar was not functional. The idea behind this guitar is to allow the musician to quickly change instruments by turning the neck. The rotation system is activated by a pedal, which allows switching from one "instrument" to another in a matter of seconds. Unlike previous prototypes, this guitar is fully functional.
