Almost any kind of electronic equipment can survive water as long as it hasn't got electricity running through it, and is dried before you use it again..
For example: I recently washed my out-of-battery mobile phone. I forgot to take it out of the pocket, so it was all soaked for almost an hour, then it was tumbledried. When I plugged in the recharger, it worked just fine. I still haven't noticed anything and it's been two weeks now.
