I'm a big fan of Great Stuff foam. One thing I always hated about it was that the foam would cure in the straw/can, so if I didn't have enough gaps to fill with one can I'd almost always have to throw it out.
I bought a can this past summer, and lo and behold this problem is no more. Dow now includes a "restartable straw"--the only difference between it and the previous straw is that they've molded a little nub into the base of the straw, so when you're done using it you can cut the straw and fold it back to prevent it from curing.
It doesn't take much to excite me, as a colleague told me today, but for someone tired of wasting spray foam I appreciate that little nub.

I'd be interested to know how the Great Foam people decided to fix the problem. Who had the idea? Who devised the solution? This looks like a simple fix -- but sometimes the simple-looking solution is in fact much more difficult to figure out.
I'm looking forward to foam-insulating the basement now!
I like it too, with a caveat: Do not wantonly spray this inside wallboard, thinking it will fill the space evenly as it will absolutely crack and destroy wallboard.
It is meant for filling small air gaps and that only.
Foam spray insulation is never done with the gypsum wallboard in place. It is sprayed over the outer layer wall, covering the studs, then leveled before installation of wallboard.
As to the non-cure tube, that is an advance, although I simply used to remove the spout and clean it with acetone when done with a partially used can.
