To celebrate the 50th anniversary of 7-Eleven’s Slurpee drink, the convenience store is bringing back its #BYOCupDay, which allows customers to bring their own drinking vessels to fill up with its signature slushy ice for $1.50, from March 18-19.

Aside from a few rules about vessel diameter, width, and height (which were largely ignored by last year’s champ, who set the bar high by bringing in his rice cooker), fans have taken delight in their own creative cup license.

This year’s MVP belongs to this stoner bro, who packed his bong with 7-Eleven’s finest green ice. We’d like to think of it as the next step in cold-chamber technology.

But he wasn’t the only one who impressed us with his sheer ingenuity. Check out some other Slurpee Scholars below:
