Glowing Twister
Many people remember Twister from childhood slumber parties; some may even still have a Twister mat stored away in the game cupboard. Renew this old game with a little neon paint. Get electric blue, bright pink, neon green and sunburst yellow craft paints at your local craft store. Use them to either paint over the dots on an existing Twister mat or create your own with a circular stencil and a few large white pieces of poster board. Tape the poster board together before you paint. You can also use the paints to make over your spin board. Make your own spin board with a white cardboard circle, a cardboard arrow and a brass brad. Use the brad to secure the arrow to the center of the circle, but leave it a bit loose so it spins. Paint the appropriate symbols on the spinner.
Laser Tag
Play your own version of laser tag under black lights. Before playing, tape a neon bull's eye to the front and back of each guest's shirt; this is even more fun if your guests change into black T-shirts before you begin to make them harder targets.
Split into teams and give everyone plastic toy guns that shoot soft foam rings. These rings usually fly pretty far and won't hurt players or damage breakable objects. Designate two areas to be "prisons" and two more areas to be "safe zones." The goal of the game is for one team to capture all of the members of the other. When a team member is hit on the bull's eye, he or she must fall and be led to the opposing team's prison. However, teams can free their prisoners if they can get to the prison without being hit.
Blacklight Sports
These games are all best if you've rented a gym or large space to have your party. Instruct your guests to wear black. Find some inexpensive sports items such as basketballs, volleyballs, baseballs and bats, badminton equipment, a soccer ball, indoor hockey equipment or net goals. Paint them all with neon or glow -n-the-dark paint. Set up each game in a different area of the party space and let your guests choose which games they want to play. The blacklights offer an extra challenge because your guests will only be able to see the equipment and exposed skin. For an even larger challenge, get all of your guests to cover or rub charcoal over their exposed skin and put on black hats. This way, they will have to watch where the balls, bats or sticks move to play.
