Self cooling energy drink

So i got my hands on a prototype of a self cooling energy drink. The company is going to sell the cooling mechanism to beer companys and pretty much any drink in a can. But basically there is a cylinder thats pressed in the can and they are reusable cylinders. You flip the drink upside down and press the button. Then you wait about 3 minutes and then flip it right side up and open. It was really cold just like it was right out of a really cold fridge. The energy drink was flippin nasty haha but neat idea. discuss.



 
it defiantly is and the energy drink is all natural vitamins nothing fake and no sugar or anything. But it will retail probably around 3.99 a can

Its a can....You can only open a can one time..But she said "they are reusable cylinders." so only the inside is usable more then once?

how does it even work??

nvm googled it. they basically create negative pressure in the can like a refrigerator, thus cooling off the drink. pretty good idea but i wont be paying 4 bucks a can for anything.
