Every carnival has the KnockDown game with the baseball and the big stuffed whatevers– and you can include it as one of your birthday party games at your next party. Perfect if yours is a carnival themed party, but it can be tweaked for just about any theme with a little computer art on the tin cans to be knocked over.
Use tin cans rather than soda bottles as they are MUCH easier to re-stack for the next player. Just print out your theme graphics, cut to the height of your cans and wrap your clean cans with the graphics as if they were a label.
Tweaking this game to your theme is easy. Animal face graphics on the cans for a jungle or safari party. Cowboys hats for a cowboy party; aliens for a Star Wars or space party; Disney princesses for a princess party; pirates for a pirate party. You get the idea.
Obviously best played outside, you just need something to set the targets up on, and the baseball or tennis ball. A 2×4 stretched between 2 sawhorses works well. So does a card table or any other kind of table that can take a little abuse is it gets hit with the ball.
Check the throwing distance ahead of time with your own child to get a handle on what kids that age can do. Lay a rope on the ground or use a 2×4 or a yardstick or even just a line drawn with flour on the grass.
Give each child 2 or 3 throws, and score by how many cans get knocked over. Have either a helper re-stack after each throw or have the kids do it when they’re not throwing.
This game shows up at every carnival and midway because it’s fun, and your party kids will enjoy it. At no cost to you and no prep either, it’s one of the easiest games you can include in your next party.
