Last week, the former welder presented to the worldhis latest creation — an upside down hair-washingmachine.
The bizarre machine resembles somewhat of aninversion table used to cure joint and back pain, with a transparent tank fitted near the bottom.
Proceeding to give his viewers a personal demo, Geng clipped his nose and placed a plastic tube in his mouth to allow him to breatheunderwater.
After flicking on a switch, the table slowly tilted backwards until his head was fitted into thetank.
After turning on a valve, water began to fill in the tank as a panel installed at the bottomstarted spinning, creating a current that ensured each strand was given a good wash.
The pamper routine is completed with a hair-drying system as well. After the water is drainedfrom the tank, hot air would be emitted to give the user the perfect blow dry.
Geng Shuai, a 31-year-old DIY tinkerer from Baoding, Hebei province, has shot to fame for his"utterly useless" yet hilarious contraptions, including a meat cleaver smartphone case, abarbecue football table and an earthquake-proof noodle bowl.
Every country has its toolshed inventors. But China — which gave the world movable typeprinting, gunpowder and the compass — has spawned a population of tinkerers who displaythe kind of outsize ambition that has helped the country become a global economic giant.
Geng may now be the best-known among them — a new kind of social media star whosecalling card is his quirkiness.
Geng is most proud of his hammer bag. It's a hollow steel mallet with a compartment thatslides out of the head. Perfect, he says, for storing your phone, keys and wallet. It has a strapso it can hang over the wearer's shoulder.
His other inventions include a 66-cm long comb made out of iron, a metal contraption thatmakes flicking someone on the forehead more painful, and a toilet built into a scooter thatflushes when you pull a lever on the handlebar.
"Most days I don't go to sleep until after midnight, I'm so busy thinking, OK, what should Imake next?" said Geng, 31, who sports a ponytail and trademark blue dungarees.
Geng is part of an industry that generates as much as $4.7bn in revenue, and one that has fewparallels outside of the country. In China, the most popular live streams are not of live eventsor the feeds of friends, but performances or shows held by strangers.
Geng tries to come up with a new invention every week and to make videos two or three timesa week. He makes about $150 every time he does a live-streamed broadcast — decent moneyin a town where five people can have a lavish lunch for a total of $25. He makes enough tosupport his family — he and his wife have two children — and his brother, who shoots thevideos.
Geng attributes his fame to China's rapid industrialization, which has seen millions of peoplemigrate from rural regions to small apartments in the big cities, where they work long days.
"Chinese people love inventions and inventing stuff, but because of economic development, most people don't have the time to do it," he said. "That's why I am popular — they watch memaking things because they can't make things themselves."
