Was planning a canoe trip with some friends when I stumbled on another instructable of water proof speakers that float. Seemed easy enough to do so I decided to give it a go. I don't eat that much ketchup, so I went with the container I had lying around, a Dutch Boy paint bucket. I used an old pair of Phillips amplified computer speakers for the sound, and used a Zip-lock baggie to water proof the hole for the speaker.
