Of course it's from Wham-O!
If you're going to do it, do it right — save your arm for pitching and add a little firepower to your winter activities with the highly amusing Wham-O Snowball Blaster. This elastic launcher features true slingshot action that fires a snowball up to 80 feet, letting you blast one of the included targets or any other target of your choosing. And since the Snowball Blaster also features a forming chamber that packs three perfectly formed snowballs, you'll be prepared for quick reloads. Ages 8+; adult supervision strongly recommended.
