Imagine a sudden heavy snowfall – you’re all trapped in your Scout Hall (or wherever you meet). You’re going to be here all night at least.
To keep spirits up every small group (sixes? that’s what they were called when I was a cub) has to devise an entertainment for the whole group. This could be a play, a dance, a game, a song, whatever.
The good thing about this is it can be extended. If you still have nothing next time they can imagine that a single person is getting out somehow, and they have to write letters home, or they can devise teams for different jobs: cleaning, cooking, etc. It’s pretty open ended, and can be returned to if needed.
I prefer to say there’s a zombie apocalypse going on outside, rather than a heavy snowfall, but it depends on the group.
