I am creating a list of all movies or T.V series which showcase float therapy. So far I've got:
1.)Altered States(1980): The film is pretty widely known so I'll just post the link
2.) Simpsons SO10 Ep 16: Lisa and Homer try the isolation tank. Pretty sweet episode.
3.) Absolutely faboulous SO1 Ep 4: An English show. More of a chick flick but the fourth episode is centered around a tank.
Any other you know which I can add on?
