Notice how the mice keeps doing it again and again. Even though in this video the guy had to make a point of the mice trying the thing again and again, this doesnt have to be that way as the bucket can be made escape proof for the little animal if we want to get rid of it. The different designs shown in the video are all quite useful, but the one made of tin cans rotating around an axle is the easiest one to make. It is actually funny to see the mouses over powering inquisitive nature getting him caught in a trap multiple times!
