BEST automotive smoke machine you can build

An automotive smoke Machine is one of the most useful diagnostic tools you can have. There’s a wide variety of different machines, but I built one with the features that I wanted. I want to see visually how much smoke is building up inside the machine, That is why I used a glass jar for this visualization. Another feature is I want to have control over how much pressure I use and when I apply the smoke. Hope you find a video useful.
