iGlow Hair Gel

After you've finished bathing in glow-in-the-dark bubble bath, maybe you want to take some of that freaky glow with you. Rather than walking around covered in suds, try getting yourself a dish of iGlow Hair Gel. This luminescent gel doesn't need UV, neon, or black lights to do its thing. A (safe) chemical reaction causes it to glow brightly for 4 to 6 hours after application, making you the hit of the rave. $8.95 USD. (Via BoingBoing.)
