Carwash in a bag ™ (old inventory)

This is an old idea that I had about 6 months ago that I came across recently when doing some move-out cleaning. It's based off of
Greenhouse-in-a-bag, a client at my old job I did a brochure for. Basically its a carwash
in a bag. It would be made out of PVC piping and when you take it out of the bag it unfolds to go over your car and spray it with water using
misters. I made a schematic for it but cant find the scan of it. I will post it
here when I do. My idea was that when you come home for the day you attach the hose to it and turn on the hose, water pressure would power
the unit back and forth over the top of your car washing it clean. Then you would fold it back up in the bag when you are done if you want.
Slight improvement over my dad's carwash garage idea he had. Anyway, just thought I would add this to the thunderdome.
