Come Together Kids: Mini Marshmallow Shooters (or Pom Pom Poppers). This one was such a total win! It's so easy and cheap to get together, and Bubba was in stitches, he was laughing so hard. He was totally able to make it work (and work well! He beaned me in the cheek with one of the marshmallows, lol), and it kept him occupied for ages!
