I save them for art projects with my cub scouts ... we put them in a sealed bag & break them with a hammer! The boys love doing that part! But don't smash 'em up too much, you still want to be able to handle the pieces with ease. Then depending on what holiday is closest, I get styrofoam shapes and hot glue gun the peices onto the shapes for a fun mosaic decoration! You could also mosiac an old coffee table using glue & grout to fill in the spaces!
