You'll never guess how camouflage helmets are made – the process is mindblowing.
Helmets are dyed with a process called hydrographics, which is kind of like printing with water, and also known as "immersion printing."
First, 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.
