Anybody use this expanding foam before?

If you have, do you know where i can get extra tubes for them at to squirt through?

I have to let it dry for a few minutes because i am filling a void about 2 cubes! After a while of me squirting waiting squirting waiting, the foam has then dried up inside the tube straw and i can't use the can anymore.

does the turn can upside down and spray til just gas comes out work with that stuff?

Drinking straws may work

i can try what acid burn said.

No, straws cant really "work" because the tube that comes with it has a base that you use to push down which lets the stuff out. With just a straw, you would have to push down on the can itself with your other hand and where i am filling this stuff up in, i can't have 2 hands at the same time in there.

I need to stop off and get some triple expanding foam today so i can ge done with it within a day or 2.

i just need to mask off a couple of electrical devices so i don't crush em and i'll be set.

It works once the can is almost empty. But before that, nope doesn't work. Been there, done that. God what a mess What I do is unscrew the little plastic hose after use, and blow air through it to clean it out. I use the compressor, but it can be done by mouth. Just put a clean rag over the tip so you don't get any in your mouth, and blow.
