Glow-in-the-Dark Scavenger Hunt
Spice up your typical scavenger hunt with this glow-in-the-dark twist. Buy glow-in-the-dark paint and cover items such as pennies, bouncy balls, sticks and rocks. The paint is hard to see, so test items before your party and expose each item to plenty of light leading up to the party. Alternatively, hide glow-in-the-dark sticks, bracelets and novelty items such as glow-in-the-dark erasers, and let participants keep what they find.
Greased Watermelon
Play this game in a backyard swimming pool. Cover a watermelon with shortening and put it in the middle of the pool. Teens stand around the edges of the pool and wait for a signal to dive in. Once in the pool, everyone races to the watermelon and tries to be the first one to get it out of the pool. Kids can try stealing it from each other too.
Backyard Sports
Teens love to play backyard games such as badminton, volleyball and soccer. Provide basic equipment, lay out the field and let them have at it.
Ping-Pong Grab
Have players stand in a circle in a backyard pool. Place a basket or some sort of container near each player on the edge of the pool. Dump a bunch of Ping-Pong balls into the center of the circle. Players race to grab as many Ping-Pong balls as they can and put them into their baskets. The player with the most balls wins.
Mix and Match
Obtain several sets of men's and women's clothes in extra-large sizes. Include pants, shirts, coats, dresses, pantyhose, hats, belts, shoes and other accessories. Combine all items in one laundry basket. Divide teens into boy-girl pairs. Each couple takes a turn racing to the basket and putting on the clothes that belong to the opposite gender (boys put on the girl clothes and vice versa). Teens put on the items over their own clothes. When each person is dressed, the couple holds hands and races back to the finish line. The fastest couple wins.
Apple Relay
Divide teens into two teams. Have each team stand in a line in boy-girl-boy-girl order. The first person on each team holds an apple under his chin. The apple gets passed down the line from person to person, but kids may not use their hands. When the last person gets the apple, he races back up and passes it to the first person. The first team to pass the apple back to the starter wins.
