Probably my biggest contribution to the world is my latest discovery.
I'm on my way to a Tampa Bay Rays baseball game and I'm blasting music through my BB and I wanted it louder so I took off the battery case.
I moved by finger over the speaker and it made a dj scratching sound! So I kept doing it... It's pretty fun if you're bored! Be your own DJ! So just move your finger back and fourth over the speaker and it sounds like you're scratching a cd.
