Eco-Blast Refillable Air Horn
If you'd have asked us what product would go eco-friendly next, we sure as hell wouldn't have said the air horn. Yet here we are, talking about the Eco-Blast Refillable Air Horn ($30), a handheld ear drum popper that runs off compressed air you push into the canister using an included pump, meaning it'll never run out when you're cheering on your favorite team, drunkenly trying to scare away trick-or-treaters, or, apparently, annoying people at chess matches.
