Hi all, i've been quiet for a while due to job changes but thats another story.

I was recently dragged along by my partner to a "Vision Health & Well-being" meeting at our local town hall, where there were various demonstrations of :-

Reflexology
Acupuncture
Crystal Healing
Hopi Ear Candles, etc, etc.

Among these demos was the detox foot spa, which my partner decided she would have a trial of after discussing various health issues it was decided she was full of toxins.

While she removed her shoes i disappeared for a couple of minuets (call of nature) and missed the setting up of the machine.

The machine was turned on and gradually a reddish brown started to appear in the water around the central round pillar between her feet.

"you can see the toxins coming out" she exclaimed, getting really excited.

Being skeptic, but also diplomatic i said "oh yeah" but the colouration in the water was quite clearly coming out of the central part.

After about ten minuets the water was really gunky looking.

My question is

Has anyone else had experience of this, but most of all what causes the stuff in the water.
