when this guy blows the pipe the little wheel at the top spins. but when his friend blew, instead of the wheel spinning, white powder came out. Actually, this tool is used to measure lung capacity by divers. which is cleverly designed with two separate air passages in the tube the main one leading to the powder discharge passage. when someone blows into it is a small hole hidden at the bottom. where a tube leads into the air to spin the wheel, and the performer blows into this hidden hole while secretly blocking the main hole with his tongue to perform the trick. • • #interesting #unique #interestingfacts #uniquefacts #tech #science #technology #explained #shortsfeed #videoshort #youtubeshorts
