Minnesota’s marijuana law continues to lag behind those of cool states like Colorado and California, which means you still can’t mention pot while buying a piece. So for now, you’ll officially have to consider the magnificent glass at Clown as merely works of art. Which, anyway, they are: The artist-created pieces — elaborate, ethereal bongs, multi-chamber bubblers, and “Sherlock” pipes — are so gorgeous, it sometimes takes a second look to realize you’re even looking at a smoke tool. Clown stands by its quality, too. On certain pieces, they’ll prove it by holding a prospective purchase out in front of a customer and dropping it onto the store’s hard floor to prove its durability. It’s a cool trick, but you probably still can’t get so comfortable you admit to the guy behind the counter you’re stoned.
