Kids have a limited view of the world. They don't understand what everything is or does. Fortunately, they all seem to know what a mousetrap is. Although few of us have actually used a mousetrap, they are shown repeatedly in TV shows and cartoons.
I have started to build a human sized moustrap out of a sheet of 4 x 8 plywood. It won't be functional, but it will store the candy on the spot where the cheeze would normally be held. I think the kids will really like it.
