Smart, creative, and fun. I like this! I know a few people I'd like to encourage to smile. But I smile a lot (idiot grin) so maybe I should make it for ME! I'd want a self-loading automatic launcher. Mmmmmm, marshmallows make me smile! Pow! Mmmmm, marshmallows ...

Fun idea! I'd smile a lot if it got me marshmallows :)
