Is it possible to only use part of a can of expanding foam for

special trick to clearing the exit-hole after the first use so it can be
used a second time?

I've used the pipecleaner-in-the-tube trick with varying results. [but
then I get a dead can about 10% of the time] Take the screw tip
off & use one pipecleaner in the top of the can. Use another in the
first section of the top. And another in the end of the tube.

If you're lucky all 3 will come out, and there will still be pressure
in the can.

A better plan is to keep a list of places where you can use a squirt
of it on the shelf where you keep you 'great stuff'.

Oh- for a can that won't spray, but still has great stuff in it? Stand
back 50 feet ad shoot it with a pellet gun. Pretty dramatic.g
