Nice! Great coverage! Shame she's not wearing more on her lower half, nice black high waist shorts or jeans would be better, but it's a cool video regardless, I even like the music!
Guess the helmet is a practical precaution against the foam, probably harmless enough on skin if washed off quickly but not stuff anyone would want in their eyes or mouth.
It got me thinking we have a snow foam adapter which attatches to hose not power washer ordered for cleaning van and cars and decking. I'm wondering if bodywash would work the same or even shampoo, would be harmless then !
