[ColorChallenge] Mystery Russian box.

Hi hi everyone! Today is friday, so we have blue color for it. I want to post this blue mystery box for you. In 70s-80s in USSR at the streets we have the same boxes. Its carbonated water machine, you put money inside and get carbonated water with syrup or without it, then you just want to drink, you can get just a normal water here for free. Here been one glass for all, and washing device. So its nostalgy, at now water is only in bottles =)
