thanks you captain obvious! lol...

very nice! I like it, looks good.

you should add a pump of some sort fixed to the side, so you pump it like a regular squirt gun.

Wel as long as you didnt hold it upside down then you should get a nice constant stream of water. As it was used to put out fires before I would assume that it would have to put out a concentrated stream and since all he did was add a constant air source I would assume that nothing would change.
