This year's prize at the SUMS Conference (http://www.jmu.edu/mathstat/sums) is a lot of jawbreakers trapped inside a 3D-printed icosahedron, symbol for the Mathematical Association of America (http://www.maa.org).

Print as a "shell" and drop in the candy before the top closes up. Make people guess how many are inside! People have to decide when/how to destroy or break the model to get at the jawbreakers.
