They're about 8", I need 24".

I know I can buy the tanks of foam, but this is a very small job.

Anyone tried extending the tips? *I tried telescoping them *together, along

Any hardware store sells same diameter plastic hose, but same size and
longer the foam will stop, get a size that just slides over the
original hose, Heating the can in hot water helps.

i tried to extend the nozzle with different diameters of clear tubing
from homedep to get to the bottom of a 4 foot cavity, but it just
congealed in the tubing.
