Kind of surprised that kids don't realize this.... What grade is it in? The first reaction I think any class I was in would have to this demonstration would be to figure out how we're being cheated. Given a bag with a random sampling of candy and being told to 'pick 5 pieces' I doubt I would choose 5 of the same large candy bars. It seems highly surprising that 100% of the time this is done you don't have a single pair of students reaching just a bit further into that bag. It doesn't even seem to be a particularly impressive demonstration.
