This Marvel fan really wanted to wear an arc reactor like Iron Man and, rather than splashing the cash, came up with a crafty way of fashioning one himself.
Using a tin of tuna, some cardboard and an old phone battery, he created this.
Worthy of Tony Stark himself.
"I wanted an arc reactor that was small enough to wear, had a self-contained battery ,and only needed to look good under a shirt. I don't have access to a 3D printer or really any special tooling. This is what i came up with (sic)," iltl64 wrote.

The arc reactor also has more than one use. "It's a couple years old now and sometimes also doubles as a headlight for my bicycle, and everything still works," he writes.
