The animator was overqualified for this job lol

[dannyzero]

When you graduate from Institute of Animation but never got hired by Hollywood

[silokhawk]

This looks great. I can't wait to see it in theaters

[djmeowth]

Everyone's talking about the great CGI for the vending machine, but I think the actor playing the part of Guy Buying A Snack did an incredible job too. He looks exactly like a person who's buying something out of a vending machine. He killed this role and he deserves recognition.

1:15 I hate it too when I'm ordering my snack and the vending machine explodes.

A one minute video and I feel like I just watched a whole documentary. Excellently done.

I did not expect a over-dramatic animation on how a vending machine assess coins but I love it

[SaltyBanjos]

1:16
*vending machine explodes*
Dude: ugh everytime

[coolpotato]

**Kid inserts fake coin**
The machine: "AutoBots Tranform!"

[man_on_wheelz]

This was like getting an excavator to dig a hole in the ground so you can plant a flower. This animator was too good for this short but, as a result, VERY informative video.

[VlerkeDamne]

This is so dramatic and over the top animated. I love it.

[Cweets]

This was wayyyy higher production then I was expecting😂😂

Science channel: "We need to hire the best animator."
Animator after getting the job: "I'm so excited, so what am I animating?"
Science channel: "A vending machine."

[thedudewithvideos]

Man the Visual Effects, Animation, Sound Effects and the Voice over is damn good than any superhero movie, wow bro you nailed it 😂😂👌🏻👌🏻
PS: Exploding of Vending machine and going deep inside 😂

[tmt]

Its really interesting that the most simplest action of using a vending machine could be so complicated the same time.

[theangrypotato.]

"This ingenius technology"

Did snack fall?
"No"
Push again

"The machine deciphers coins with pin point accuracy"

Me putting my quarter in for the 4th time: ಠ_ಠ

[gabrielcosta]

About 10-15 years ago we had a machine like this at school, somehow someone figured out that if they disconnected the machine from the wall at just the right time, it wouldn't detect the product being dispensed, and just returned the money, needless to say it wasn't long before the machine got disconnected entirely for not making money

[Andyelmasry]

I love how overly high quality this animation is, like dang man great job

[benw]

Yet it can't read my pristine dollar bill that I've put in every direction physically possible
