More ballistic than bubbly! When Brittany Snow tried to promote Lipton's new Sparkling Iced Tea, she ran into some problems. 

In the funny new commercial, the demanding director instructed the Pitch Perfect 2 star, 29, to be at a "bubble level 300" while endorsing the "tea with tiny bubbles." But try as she might, Snow couldn't seem to make it work. 

The perky star struggled with being bubbly enough for the new kind of tea, and eventually blew up, cursing at the director and destroying the set. 

The director then brought in the band American Authors to sing a jingle, but Snow interrupted them too. Watch the funny clip to see what happens!
