Looks like a lung test… but it’s actually a trap.
This old mining “blow-back pipe,” demonstrated by Clive Panto, was used in British mining communities as a crude way to test breathing strength—but it hides a clever dual-path mechanism inside. When demonstrated properly, the user seals their lips and blocks the main opening with their tongue, forcing air through a hidden secondary channel that spins a small wheel safely.
But here’s where it flips. Most people naturally blow straight into the main pipe without blocking that opening. That sends air into a separate chamber packed with fine powder like chalk or flour, which then shoots back out through a concealed vent—right into their face.
Same device, two completely different outcomes—depending on how you blow.

literally the oldest trick in the book
You have to blow slowly at first to get it moving
“Shucks you got me! It appears that I am now covered in Asbestos!”
Suck, don’t blow.
Well old Bean, you just hit me with the Fetty blaster 3000! I'm dead!
One is through the nose I'm guessing, the other through the mouth.
The first guy sucks
Well I’ll give this splendid doodad a jolly good go- GOOD HEAVENS
There's a small hole you need to cover with your thumb to seal the tube going to a secondary hole that the powder shoots from. Unseal that hole and air flows past it into the powder reservoir. blowing very lightly will also not cause it to eject the powder so you can show them a second time and say, "I can't get it to work this time" and see if they'll fall for it a second time.
Man, I love stealing classic videos and stamping my name above it
For those who don't know, wich y'all probably know
The secret is to block the hole with your tongue so the air goes through another hole wich won'tr shoot the coke- i mean flour at you
Did the other guy blow through his nose then?
Old chap blows with the back of his throat.
Hahahahaha.

First guy sucked in, you can tell cause his cheeks are sucking in
Hole on the side, one covered, one didn't.

The first guy sucked it in, the second guy blew it
