Hi everyone. Firstly, I know that this isn't an AIBU question, but this is the board I'm used to and you generally get excellent replies. So I'll don my hard hat and go for it 
Part of my job - in a deprived school - is running a club for the youngsters (7 10 year olds in particular). I'm free to do what I want with them and last time we decorated and ate cakes. They loved it. Next week will be the last time I'm running the club, and they have asked to do a food based activity once again 
Points to consider:
- I'll be paying for it myself
- I don't mind that
- our time is limited. Like, half an hour tops.
- it can't be too messy and I don't have a sink in the same room
Any ideas for food based games or activities that are cheap, not too messy or lengthy?!
Thanks.
