Although I'm not a huge fan of FRS radios, it does come in handy from time to time, especially when we're camping and want the kids to take a radio with them while they're exploring around. The problem is that they always put the radio down, drop it in the ocean or lake, or just don't hear it. This looks like it could be a practical, inexpensive solution to that if you only need short distance communication:
