Depending on what affect they really need (meaning is it just the color and fluidity of what they are running through, or does it need to be dripping off of them as they wade through…) maybe something floating on top of plan treated water would be better. What comes to mind are those little ping pong like balls you float on top of water baths to keep the bath from evaporating too quickly. Something smaller, but the right color and with the right surface tension might work…

This seems pretty wierd even to me and my wierd-o-meter hasn't been pegged at the red line in more years than I care to think I've lived through.  The whole thing just seems plain silly if not totally dumb.
That on whoever's Green Earth would this be done for?  I mean Art is Art and some of us have been pretty artsy-fartsy over the years, but this is much more excessive than I've come accross since they originally stages The Fantastics.

I mean, OK for Andrew Llloyd Weber and various theatre effects, but WHY?  The think the Bad Count Dracula or even "The Impaler" on whom it was somewhat badly historically based and someone thinks they need to take a bath in virgins blood to preserve their youth (total BS).
Maybe in my old age and having been hanging around the DC area with a bunch of plumbing engineers and similar good folks for a few days working out changes to the ISEA/ANSI Z358.1 and related 113 Standards have addled what little remaims of my brain, but this seems rather incredibly silly.  Any way to explain it that a mere mortal might understand?
My Worthy Opponent (and everyone needs one/found an Army guy to play chess with this evening and he beat me 2/2 because we both needed some sleep to get in the 3rd game).
I would try and work out the tox and safety issues, but my initial impression is to say:  "Hell, No!"

In my former job, I was actually required to become a Certified Pool Operator.  That was more than ten years ago.  Therefore, this is based on memories from over ten years ago.  Does the pool have a circulation system and a filter system?  If not, it isn't a swimming pool. The water will never reach proper balance, and it will be a bacteria infected mess that I think isn't even legal for people to enter.   


If you go to the PubMed website and search "swimming pool chemistry", you should retrieve 199 citations.  This citation should be in the lower right corner.  It looked relevant.


Here is the link to the 199 citations:


If it doesn't work, try the search yourself.  I think you might be able to find some good info.  If you need further help, please let me know.  Good luck.

Once again I'm hoping you all can find someone who can help with a problem that would cross a Rabbi's eyes.

A famous theater in NYC is planning a production in which people will wade through a 1500 gallon pool of "blood"  a few times a week for about 6 weeks. They've been doing some tests on a mixture of commercial stage blood diluted 1:10 with water.  Since stage blood is made with a lot of dyes, corn syrup, propylene glycol and methyl parabens, and since diluting it will cause the parabens to fail, and since they will be using this over many weeks at 90 o F and regularly introduce the living organisms from a bunch of feet, they thought they could used pool chemicals (mostly sodium dichloroisocyanurate) to keep it from functioning like a giant petrii dish. 

However, in their "tests" the amount of chlorine just doesn't get up to a safe level.  I'm not surprised since dyes are high nitrogen compounds, there are organic chemicals presents, etc.

I'm also concerned that the dyes are fading with the chlorine application and breaking down.  That means there may be small amounts of some really toxic stuff in there.

This is beyond me.  I can help with the dyes, but they need someone who can figure out more about the chemicals likely to be created in this soup and if we need to look in a completely different direction for a solution to this problem.

I'm taking names and suggestions from one and all.
