I was watching foam machines and how ultra-simple it is to make one:
So, rather than soaping a public fountain to make gobs of foam (they don’t seem to like that), I whipped up my own foam machine in about 5 minutes. Within less than a minute, I had more foam than I really wanted in my house! hehe The cats were unimpressed.
I hooked my shop vac hose to the blow side, put a sock over the end, inserted the spray end of a hand-held pump-up garden sprayer along with it, and I had foam. Lots of foam.
Well now… I also have a very powerful floor fan that is just about the size of a burlap bag or pillow case (course cloth makes more “dry” foam). Too bad it’s winter, but spring is coming - gonna make my house a giant “spittle bug”!
