The Kooty Key – A Wacky Device That Helps Germaphobes Keep Their Hands Clean

Developed by champion bodybuilder and auto parts salesman Ken Kolb, the Kooty Key is a handy little tool designed designed to help people avoid touching germ-infested surfaces like door handles, ATM machine keyboards public toilet faucets.

Ken Kolb says that he spent most of his life as a traveling salesman, and the years he noticed how air blowers in public restrooms were replacing old paper towel dispensers. While the new technology does have it advantages, it also prevents people from using the paper they would wipe their hands with after washing them to open the bathroom door on their way out. This he claims increases the risk or re-contamination, so he took it upon himself to come up with a solution. That’s basically the short story behind the Kooty Key, a small hook-like plastic device that allows germaphobes to interact with potentially-germ-infested surfaces without the risk of contaminating their hands.

Teenagers Create Innovative Door Handle That Kills 99.8 Percent of Germs

A couple of teen geniuses from Hong Kong have invented a product that could revolutionize the world of hygiene and infection control. They’ve created a door handle that instantly destroys germs every time it is touched by human hands.

The two kids – 17-year-old Sun Ming (‘Simon’) Wong and 18-year-old King Pong (‘Michael’) Li – are students at Tam Lee Lai Fun Memorial Secondary School, in Tuen Mun, China. They realised that everyday objects such as doorknobs, handrails, shopping cart handles, and counter-tops are breeding grounds for millions of germs, so they set out to explore the possibility of creating self-disinfecting surfaces that remain germ-free all the time.

After considerable research, Simon and Michael found out that titanium dioxide is an amazing bacteria-killer. So they ground the mineral into a very fine powder to use as a coating for the handle. They also discovered that titanium dioxide is more effective when exposed to ultraviolet (UV) rays. This posed a challenge: sunlight is a natural source of UV rays, but door handles are generally used indoors. So they had to come up with an energy-efficient artificial source of UV rays.
