There are a lot of great things about the age we live in. One of my favorites is being able to take my music with me almost anywhere. Sure, we’ve had portable CD and cassette players in the past, but those were severely limited in their storage capacity, and they were bulky. But even they have their limitations, notably when you want to blast your music loud enough for an entire room to enjoy. If that’s a situation you run into very often, you might check out this Rock-It 2.0.

This is the second iteration of the Rock-It device (as you might have gathered from the name), which means that it’s been improved in a number of areas. So what does this thing do? When you plug it into your music player (anything with a standard headphone jack works), there is a sticky pad that you can attach to virtually any object. Once you do, the Rock-It turns that object into a speaker. What it does is vibrates against the object, which causes the sound waves to become amplified by the object. Naturally, hollow objects work best. Just $50 and AA batteries turns almost anything into a speaker. How cool is that?
