My Highlighter Gun

I saw jsr pen gun and decided I wanted to try my own. The only tubing I had was some .177 bb tube so i fit it inside a pink highlighter. For a piston i cut up a nerf dart, it seals really good. It goes through both sides a soda can. I run it at about 100 psi up to 150.

How does a highlighter body hold 150 psi? Ive never heard of pressure rated highlighter's...
Paint it all black, and it would look so much better.

I think the small chamber lets it take higher pressure.

Yeah i have the cap, but ill have to sand down the epoxy on the end if i want to put the cap on both sides, Im worried if i sand it too much it might get weak.

Cool..these little menaces are sprouting up everywhere. I'd mind that chamber though, especially seen as it's probably a hard plastic that will shatter rather than split on failure.
Good work though
