Tired of riding your bike through crowds that won't get out of your way? Distracted drivers that veer too close? One blast from the Thunder Horn and you'll have a clear path for miles.

Not a toy (or recommended for kids at all), its pant-soiling 115 decibel sound output is just a little louder than the sound reaching your ears from the front row of a rock concert (110 dB), and just below the "threshold of pain" (130 dB). And for those of you who were wondering, 160 dB results in the instant perforation of the eardrum. It'll be the last time you'll have to yell "EXCUSE ME!" over and over as you're forced up over the curb.

(Since it's battery operated, and can go anywhere, I'm thinking how insidious this thing would be in a an office environment. "BWEEEEEEEP!!!! Bob, where's your TPS report?!")
