  1. A year ago: YouTube recommended this to me.
    Few months later: I watched this again.
    Today: FINE I’LL WATCH IT FOR THE 100st TIME!

  2. "How Do Vending Machines Detect Fake Coins?" Dude, they CAN'T tell fake coins from real ones. The "electromagnetic detector" is just a magnet that sorts magnetic coins from nonmagnetic coins. In the USA all coins are non (ferro) magnetic whereas in many other countries (like EU) they're ALL magnetic.

  3. Ha guy I used to work with ran a sheet lazer he made disks same dia. And thickness as a quarter then drilled holes in them to make weight… he only got caught cause he used one at work…

  4. There are some Thai coins which are exactly like 2€ coins. Vending machines in would except these Thai coins as euro coins

  5. False I put one of those fake plastic toonies from a math set in a vending machine when I was in elementary school and I got a free pop out of the machine on multiple occasions

  6. Mythbusters: So, inserting a coin with a wire tied at one end to the coin, and at the other to your finger so you can pull it back again won't work.

  7. But does it detect currency from different countries because are vending machines in different countries programmed to accept the countries own kind of currency like for an example would Canadian dollars not work in a vending machine in the United States

  8. I guess the machine I've used back then weren't told that's how they were supposed to work, instead of refusing too many real coins and making food be stuck.

  9. It doesn't work that perfect on my purchases. My biggest nightmare is when my potato chips are leaning against the inside window, and never fall. I'm shaking the machine in desperation to get my treat unstuck. I fear if I leave, the next person coming will select the same item, and get two bags of chips. More machines take credit and debit cards, so less of a worry there. When I was a kid, I would file down a penny into the size of a dime. A lot of work to get the coin to work in a pay phone. :/

  10. Not my machine, if the snack doesnt fall and gets stuck against the glass, u lose that money. U can call customer care but they insult you for being petty over a dollar.

  11. this is a terrific video; short, sweet, and to the point.

    if any modern youtube personality had made a video with this same title, it would be like 10 minutes long and end with "DON't FORGET TO LIKE AND SUBSCRIBE"
