Papasmurf has an excellent thread about starting a cheap scouting hammock kit that might be worth looking into. Getting the scouts to make their own inexpensive hammock setup could be a fun activity. He also has his own website with some cool diy gear ideas. The scouts learn some skills, AND get to use what they've made to make their camping experience more enjoyable.
I was a lot happier not knowing that alcohol stoves are outlawed for scouts. I make them; I use them when I camp, and would love to get my scouts working on some (what's more awesome than fire projects?), but now that I know... I know. I might still get them working on a diy bushbuddy woodgas stove--not quite as easy, but still pretty cool.
