Where does that extra square of chocolate come from? Try to come up with an explanation, and when you think you’ve figured it out, hit this link.
One piece gets longer
I wish this would work! ^_^
The solution link animation doesn’t make it at all clear. BOTH big chunks get longer as they move. Hard to catch, but if you watch the smallest sliver piece of either larger chuck, you will see it grow as it moves. I honestly don’t know what the “solution” link is trying to point out.
If only I could do this with real chocolate.
