[Howdy everyone. As milkweed* sagely pointed out.. You should not attempt to give yourself a tattoo. Just wanted to emphasize this. - Leah (the craftster admin)]
My friend and i always wanted to try making one so we did today..
It woks but obviously we aren't going to use it on anyone, don't worry we aren't stupid enough to give ourselves (or anyone else) infections.
Its just to practice on fruits.
Heres the gun:
and the orange i was tattooing:
Its made from a pen, an eraser, a motor from a RC car, a guitar string, tape, a battery, and a toothbrush.
