BELLINGHAM, Wash. — Bottles of legal marijuana-infused soda delivered to a Washington state pot shop started exploding on the store shelf.

The manager of Top Shelf Cannabis, Zach Henifin, told KOMO (http://is.gd/CvX0bS ) that "it sounded like a shotgun going off."

No one was injured at the store in Bellingham in northern Washington, where recreational pot is legal.

Henifin wore a face guard and protective clothing to move more than 300 bottles to a steel trash bin and most had exploded by Tuesday.

The sparkling pomegranate soda was made by Mirth Provisions and delivered on Sept. 28. Employees found a sticky mess the next day and heard and saw bottles randomly explode.

Mirth Provisions founder Adam Stites says there was too much yeast in the soda and fermentation caused excess carbon dioxide to build up.
