How do you get three inches of snow off the top of the tear, the well water is at 55 degrees
How you get the air in is, what ever works for you. In my case I use the two 400 CF bilge blowers that are used with my HEPA filter and air conditioner.
What I found, and how do you mark it. Shooting bubbles is like shooting glass, very difficult with out the right lighting, oh well
Dry erase marker will survive a good rain storm and wipes off easily, you do need to wipe off the dish washing soap first (I prefer Dawn in water).
