If you’ve ever wanted to fill that heirloom gravy boat with a Slurpee from 7-Eleven, now’s your chance. The convenience store is hosting a BYOB event for the sugary, icy drink starting this weekend. 

As part of its celebration for the 50th birthday of the Slurpee, 7-Eleven will allow customers “Bring Your Own Cup” to stores from 11 a.m. to 7 p.m. Saturday and Sunday, Business Insider reports.

While you might be thinking of filling an inflatable pool or 10-gallon bucket with the sugary drink for $1.50, the company has placed a few limitations on the promotion.

The cup “must fit upright through an in-store display with a 10-inch-diameter hole,” the company tells Business Insider.

While that means that kiddie pools and trash cans are out, it also means you’re free to fill up mixing bowls, hard hats, and teapots, with some Slurpee.
