Anyone made a smoke machine yet ?

I'm curious if there's any ideas on this - I heard dry Ice becomes fog at room temp and could be used to smoke test, but I'm not sure .. open to ideas

To check for exhaust, vacuum, or boost leaks?

How about dry ice in a soda bottle with some water and drill a small hole in the cap (don't forget this step).

Smoke test is ok but it doesn't pressurize the system so it will only show obvious leaks.

Some boost leaks won't show up until the route is pressurized because things start expanding.
