Thanks for this revelation. It has a name! All my siblings got these and they told me “it’s a gas in your lung” which i ran with for years, haha. Once, still as a kid, i got it for 6 hours so we called a doctor. She diagnosed it as intercostal neuritis triggered by high and unusual physical excertion the previous day. Prescribed nothing

As depicted in the op, they make artistic sculptures/scenery that amaze people.

Looks the same to me

Am i the only one that finds this terrifying as a pedestrian? All the people in the video had to stop when they arrived at the intersection and wait for a car to allow them to cross. If someone were crossing here unaware and started crossing immediately, this thing could hit them anywhere up to the face. And that is if it doesn’t have enough force to make one loose their balance or straight up catapult them. I refuse to believe this thing is actually just active and without supervision. I think they just deployed this thing for an afternoon to get the shots and coached the pedestrians. I find this anything but brilliant

They’re all ghosts now
