There's a few of these knocking about but that is one of the best.
 
How do hand dryers tell the different between human flesh and an inanimate object such as a plastic cup?
 
So you're telling me a plastic cup can just wander into a bathroom and use a hand drier?

Utter woke nonsense.
No it can't. But when I hold an inanimate object under the hand dryer to dry, it doesn't work.

I have even tried fooling the hand dryer by activating it with my hand and then quickly switching it with an inanimate object, but the hand dryer is too smart to fall for that. I don't know how.

My next step would be googling the make and model number to find out exactly how it performs such witchcraft.
 
Well @Nancy I did indeed do some googling ... the dryer uses an infra-red light and sensor, when hands are placed underneath it bounces the infra-red light back into the sensor which switches the dryer on. Infra-red light can pass through thin plastics so the sensor isn't activated and the dryer stops because it thinks there's nothing there.

Not witchcraft at all, it's just science.

Tomorrow please try the same experiment with other inanimate objects of varying materials, I'm invested now.

I just did the same Google.

What exciting lives we live

It isn't unusual for me, I love knowing how stuff works. The IT bloke was aghast at some of my bookmarks on the work computer, he said Mammoet sounded a bit dodgy and asked if he should delete it so I told him to click it. Heavy lifting machinery and transportation, he didn't seem impressed with the cantilever wheels on the trailers so I made him watch a video :D
 
My toxic trait is not being able to simply marvel at the wonder of the universe, I have to google things to find out how they are done. I am so full of pointless, useless information.
