12 bizarre containers for
7-Eleven BYO Cup Day

Keep your Slurpee safe in a construction helmet.

Chelsea Frisbie

For $1.50 you can bring your own cup to 7-Eleven on March 18 and 19, and fill it with your Slurpee of choice. So long as you abide by the rules, you can fill anything from a Frisbee to a flower pot with your favorite flavor...or a combination of six. The event is a celebration of Slurpee's 50th birthday, though this is the second year 7-Eleven has allowed customers to BYO cup. The drink is a cult favorite at one of America's most popular convenience stores. Mashable headed to the nearest store with 12 creative cups in tow, just to see what we could get away with. The chain gave each of these a thumbs up, even the red wagon.
