Making a camouflage helmet is more mesmerizing than you might have thought.
Helmets are dyed with a process called hydrographics, a specific type of printing that sues water, also known as “immersion printing.”
To start the process a “thin film made of polyvinyl alcohol is printed with the camouflage pattern, and placed above a pool of water. After about a minute, the film dissolves into dye, which is when the helmets are dipped into the water,” Business Insider explains.
The process can make different patters and also works on different materials.
The United States military still uses fabric for camouflage, but that could change in the future.
