WATCH: Man breaks glass with his voice
A man shocked himself and his friends when he broke a glass using his voice.
We've seen several videos of people claiming they could break a glass by singing or screaming at high pitches.
Some fake it, but this man was shocked when he actually achieved his goal. Justin Klein learned how to do this trick by watching 'MythBusters' and made a bet with his friends that he would be able to pull it off. Klein is a singer from Wilmington, North Carolina, and could luckily hold his note for a long while.
