Beware of brittle chambers...

Allright, so I build my first combustion a few weeks ago. a SMALL pill bottle. It was nothing. So I got a bigger bottle, and a better sparker.. It worked pretty good. Some air leaked around the barrel, so I hot- glued it.


I guess that was a bad idea, because I shot it today, sealed off, and it blew up in my hand. Completeley blew off the 'bottom' of the bottle, and split the top.

It hurt a bit, but I was holding it just right. When you go and make your guns- make sure you dont use the brittle plastic...

yes a pill bottle is not rated for pressure so it will burst if the barrel is too small

:) my ghetto gatorade gun wich has been scraped once couldent relive the pressure because the bullet was stuck so it burned the bottle melting the plastic and burning the sh1t out of me i was so pissed i smaked the bottle all over the place.
