Venturi vacuum pump

[iceminion]

I feel like additional explanation is needed. I am not trying to push a product to make a huge amount of profit, I am offering knowledge that I gained through trial and error.

I know I am not the only one with this problem, I kinda wish more people would have chimed in with "yeah man, same problem here, can i buy one/tell me how you made it?"

again, just trying to help with a problem that is not really covered enough (in my opinion)
