Let's face it: We are music obsessed and addicted, thanks to the relatively recent birth of iPods and other rattle-proof MP3 players that have become part of the fabric of life. And a compact new gadget makes it easy to broadcast your own soundtrack anywhere, even biking, hiking, or camping.
Rock-It ($49.99) is the first ever portable vibration speaker that will turn anything into a speaker. It turns music into vibration sequences and sends them through the Rock-It pod, which you can stick to any object and turn it instantly into a speaker. It also weighs only ½ lb and small enough to fit in your back pocket.
We haven't yet tested how well Rock-It would stick or sound while attached to a tent, but assuming it's not damp, we think it has a shot. The company recommends cardboard boxes, hollow objects, lamp shades, plastic cups, and windows.
