A bean bag (beanbags) is a sealed bag containing dried beans, PVC pellets, expanded polystyrene, or expanded polypropylene. The bags are commonly used for throwing games, but have various other applications. Bean bag toss (or cornhole) is a game similar to horseshoes and quoits, played with bean bags and two goals. Footbag (also known as Hacky Sack, a trademark) is a type of ball shaped bean bag that is used to play various games. Bean bags are also commonly used for juggling. In gridiron football beanbags are used to mark the point of a change of possession (where a punt or kickoff is caught, an interception is made, or a fumble occurs). Bean bags are often used for a game similar to dodgeball where small square bean bags are slid across the floor with the object to hit the opposing team's players in the foot. The game is particularly popular in American elementary schools as a safer alternative to dodgeball. Bean bags are simply just fun.
