I suspect that there are two dangers to be concerned with VS getting solid state electronics wet. First is corrosion of exposed wiring. Second would be shorting out the circuits. Given that the majority of the circuitry is within the chip and therefore not too exposed It is rather simple to just dry out the gadget before applying any current. As long as the gadget is dry when the current is applied then all will be well even if it got wet prior. OTOH, if there is any water present when the current is applied I would expect fatal damage to result. If your gadget has no on-board battery it will be fairly impervious to damage by dunking. there are no moving parts so you can knock it around a fair bit as well. but if you get it wet then it is imperative that you also get it dry. So if it goes in the laundry make sure it goes in the dryer as well.
