This is the coolest thing in 2013 so far, and it might take some time to replace its place! Re: Sound Bottle is an auto remixing item that can record any daily sound and then automatically remix it into a beat-like music.
Simply open the lid and it records sound. Close it to stop recording. Add as many random sounds as you like, then hit the remix button and the bottle will automatically remix everything it has heard, and play it back when you open the bottle. Definitely cool!
