Oh I think it is wonderful, stays slippery.  I don't see how you can be alergic to seaweed!  it is tasteless and tho thicker than water, very harmless. 
Clean up from your body, just wash/shower.  No problem.
I have solved a problem with the "container" too big.  I figure my smaller solution will work for 6' and under.  I will have all that worked out by next Tues. 
The shower curtain seems like it would slip off the bed (and everyone one it)  if not tied down.
I will be meeting my source toulmin 

 tomorrow.  I couldn't "out" him till he mentioned it himself. 
So I should be ready to "slip and slide" by Tuesday. 
I would prefer to offer this to those who have met with me before 
but I D.E.W. not believe that I have met those who expressed interest here or in PM. I think this is best set up by PM. 
I can also see that if a guy could pick 2 gals that could be a huge blast.
