Disposable bamboo sticks — use them, then burn them.

The appeal is no cleanup. Melted marshmallow welds itself to a metal fork and you will be scrubbing it at the next water point. A bamboo stick goes in the fire when you are done.

Good for groups and for anyone who would rather not carry sticky metal home in a camp box.

Biodegradable, so what does not get burned is not a problem.
