The crazy way patterns are put on phone cases is like nothing you've ever seen

The way patterns are put on phone cases is absolutely mesmerizing.

Patterns are put on phone cases through a type of printing, but you won't be able to do it with your Inkjet at home.

The process it called hydrographics, sometimes known as water transfer printing.

It's basically printing with water, and works on pretty much anything, from toys to helmets. 

HG Arts, a company that makes hydrographic printers, showed us how the process works.

First, blank phone cases act as a clean slate.

The phone cases are then suspended above a pool of water.

A thin sheet made of polyvinyl alcohol is printed with the desired pattern, then rolled over the pool of water.
