Swaps are little crafts that are put together for Twilight camp with the idea of "swapping" them with other scouts.

For twilight camp scouts are expected to bring a "bucket" seat. It's a 5 gallon bucket with a lid... and you may or may not add padding to it.

Once you have your bucket you can choose to paint it or otherwise decorate it to your choosing.
