It doesn't matter how old you are, glow sticks are always cool, and the science behind them is even cooler. DIY website Instructables show us how to make our own.
You only need about five different chemicals for this project, which you can get online, and there isn't much to it besides mixing them all together. It's not the most cost-effective way to get your hands on some glow sticks (though you can make one of the chemicals yourself if you want to cut costs), but it's definitely a fun and educational project. Check out the video to see them in action.
