Are you sure you used epoxy?
Cause the milky color in the adhesive dangerously resembles hot glue...

lol, and the Gatorade bottle wasn't?
not trying to be harsh or anything, but just concerned about your safety.

But yeah, once you slap on a good ol' 2 liter coke bottle on there, it should be plenty safe and FUN :D

Word of advice. Stop filling it with air when it starts expanding. I hope your like most people and use your commom sense...Thats why we have it. 8)

EDIT: BTW I like the design... Maybe spray paint some decals on the bottle, I would prefer flames, but thats me. Also...Did you epoxy the scrader valve? Because thats the most likely part to give in and shoot out. Ive been hit by the valve under the same exact cercumstances and lemme tell you, I hurts like a mofo.
Have fun

Well then again, you threaded it into the bottom which is pretty strong. Well just makin sure cuz I dont want to hear that you died because a schrader valve went through your jugular vaine.

why don't you add a few cm of pipe (or a tee ) between the bottle and the valve and put shrader there ?

Agree, but even better, replace the whole chamber by a piece of pvc.
