orcishgamer: I've had DS games make it, taped them to a ceiling fan for a couple of days and let it spin on slow.
I also half submerged a DS which lasted until it got dropped and cracked a year later (actually it sort of still works). I had to take a bit of it apart and let it dry out, but it worked.
Sometimes electronics are pretty well made. Of course it depends what you dip them in:)
That used to be fairly common, these days I'm not so sure. In olden times the amount of charge stored in the battery was insufficient to fry the circuit, the worst thing would be oxidation or any damage from a chip running out of spec.
These days I'm not really sure, batteries have gotten a lot more powerful in recent years.
