DIY Foam Machine

2023 Update!
I have been tinkering with foam machines over the last few years and I want to get more out there for all of you. Please leave me a note on this google form so I can gauge interest and send you information about my foam machines!

Some points I forgot to go over in the video:

Total cost was around $300 I think the most expensive component by far being the blower. The only place I see the blower now is on amazon (Q standard 16" 1 hp utility blower) but it is significantly cheaper than I got it for. I think this blower is the best deal and shape for the this project with the power you get. I think you need the 1 hp. I wonder if 3/4 hp or so would work but I don't think I would risk it.

The fabric is very important. The setup that I based my design off of used landscape fabric but apparently they are not all created equal becasue mine didn't work. My fabric was an old blanket and it is not a very fine weave so you will probably have to experiment to find something that works. If water is pouring out the bottom of the fabric and hardly any bubbles that means your fabric's weave is too tight.

You may want to experiment with different types and concentrations of soap. I have used a lot of soaps but never done and actual test to see which ones work best or at what concentration.

Finally this is super fun, for kids and adults, who doesn't love a mountain of bubbles. Putting a plastic sheet or slipnslide going into it is fun. The 30 gallon barrel will last for about 15 minutes and probably fill a 15x15x10 ft area in one run if the bubbles are undisturbed. The 1/3 hp pump may be overkill, maybe 1/5 hp or less even would work but I just don't know. And put all the soap you want into the grass, you're not going to hurt it.
