Light Fingers are ridiculous.
A hypnotic light show at your fingertips; put on your favorite music, turn down the lights, and dazzle yourself with beams of pure color. You control more than 20 different pre-programmed light show patterns, plus a black light and strobe light add mind-blowing effects.
They cost $20 and will make you the stupidest looking person at whatever party you're at. Since when did a glow-stick on a string become insufficient entertainment when you're tripping? They always worked fine for me. Well, except for the one I chewed through. While having a glowing tongue is kind of cool for a minute, it isn't worth the taste of radioactive shit in your mouth.
