Clean Hands Assured

Claude Davis of Melbourne, Florida obtained a patent for this curious device in 2000. It seems newly relevant in the era of coronavirus.

The gadget attached to bathroom doors. Whenever someone turned the handle to open the door, the gadget would spray their hand with dye. This, reasoned Davis, would encourage people to wash their hands, to remove the dye. He imagined his invention might be useful in restaurants and hospitals that have "statutory type hygiene requirements to have their staff and employees clean their hands after using restroom facilities."

Although the invention had good intentions, I can think of several problems with it.

First, I'm sure that most employees would find it incredibly obnoxious to have their hand sprayed with dye every time they went to the bathroom.

Second, wouldn't the gadget also spray dye whenever someone exited the door... spraying into empty air? In which case, half the dye would be wasted. I can imagine employees standing on the inside of the door, pumping away at the door handle until all the dye was used up.

The first problem I see is you have dye on your hand, dye which is going to transfer to whatever you touch. Try explaining to your date why your nether-regions are a bright red . . .

The damn thing victimizes just one person, who blocks the door open.
