For Scotty McCreery, who celebrated his 18th birthday Sunday (Oct. 9), it was his unusually deep voice that captured viewers on last season's American Idol, and ultimately the top prize. During a recent visit to the The Ellen DeGeneres Show set, the host set out to see if the voice-changing element helium could alter the teen's basement-deep voice. "Mama says [my voice] fell off a cliff about [age] 13. It skipped that cracking stage so I skipped the teasing, too," said Scotty.

Ellen asked Scotty to inhale from a helium-filled balloon. While Scotty's voice was slightly higher, it was nothing compared to the high-pitched, squeaky speaking one would expect after inhaling helium. Ellen also took a hit of the helium, with typical squeaky-voiced results. After the effects of the helium wore off, Scotty performed his current single, "The Trouble With Girls."
