The glow-in-the-dark dart blaster was first invented in 1997 and was called the Max Force Electric Eel. The Eel had a translucent clip that helped these bad boys to recharge without having to leave their place or left out in the sun.
This phenomenon was later touched by Nerf again in 2003, through the release of the Micro-Darts. The trick behind getting these neat little bullets to glow is sunlight, or the Firefly Tech clip to keep them recharged. These nifty darts are sold in packs of six, eight, and even 12, or 16. They are a sure-fire way to have fun in a low-light setting.
