24 hours underwater

[Woz]

Other ideas:

Underwater MP3 player. Brilliant bits of kit.
Do a search on Amazon for "Aqua Erotica" and "The Beach Book". Both printed on waterproof paper. The Aqua Erotica is a bit distressing though as the couple you thought were getting it on and giving you a bit of a woodie are, in fact, both blokes. The Beach Book is a collection of short stories.
Sudoku. You drop down at least 2 levels when underwater. So take "easy" ones.

Apparently the main probelm with underwater records is the exposed skin waterlogging then sloughing off your flesh in attractive sheets leaving raw red flesh. If you talk to the bloke at the NW Hyperbaric Unit (the one that looks like Lister) they will fill one of their chambers with water with salts balanced to your body so you don't get the waterlogging effect. Tanya Streeter uses them for training, apparently.

We took down some cards which had that sort of plasticky finish to them, thinking they'd last. They did....for about 10 minutes, then it wasn't so much a game of 'snap'' as a game of 'sludge'

We also had some little magnetic 'travel' games. Chess, draughts, snakes and ladders, that sort of thing. Just make sure you have dice which sink not float! I think we got them from WHSmith - only a few quid each and a godsend after 8 or 9 hours....

Really, don't bother with the frisbee...

Sonys PSP can be "vac-packed" and used as well

I believe some Italians spent almost a week underwater and used these for viewing movies, games and messages of support.
