text: if i throw a radio into a tub of water, how long before it is safe to pull the radio out?   if it is a battery powered radio you should be able to pull it out without getting shocked (unless it's using some pretty powerful batteries).  if it plugs in to the wall unplug it, wait a couple of minutes to be safe, and pull it out.  but i think the real question is: why would you throw a radio into a tub of water?!
