16 children due to arrive in a few hours (aged between 2 and 8) for a 4th birthday party. The bouncy castle has arrived and the outdoor games are planned.
The weather forecast has changed from ok last night to awful this morning.
I have a few prizes available, but need some quick ideas of how to keep them occupied inside that don't involve me going and buying stuff.
Please help! (and yes I so know that I am stupid for not having a contingency plan)
