i remember my mars bar got stuck once in a vending machine. and a random strong albanian came to me and said "soo.. its stuck?" and i said "yeah" then he started shaking with the vending machine and even things i didnt pay for started falling down. then he said "today everything is free." and then he left. he didnt even take something. i just remember that it was very random. (i'm also not sure if he was actualy albanian. just have a lot of albanian friends. he could be from kosovo or serbian idk.

'Puaple' 3 months ago
just get the machine stuck. if there's your snack stuck on the window, order one higher, the vending machine will think that it didn't vend, then it would keep on dispensing

toss a Canada quarter in a us vending and I bet most of the time it will take it. what bad is you can buy Canada change for less then half its value and their is no law saying you cant use it as the only laws that prohibit it has froud is using fake coins

darkness blade
'darkness blade' 4 months ago
well then its back to the old gatchapon machines with 3d printed coins.

since its not yet possible to create a exact copy of a coin using filament.
1 due the different materials
2 due the offset of like 0,001. (printers can go up to 0,01 or 0,02)
3 not every printer has multiple extruders
4 not very cost effective using 3d printed metal coins

1:01 "and release your snack, at the touch of a button"

Absolute bullshit, I have to fight the machine first. I know of no vending machine that simply JUST releases your food once you have paid for it.
