A late, and perhaps controversial, entry into this season’s frozen treats giveaways, Dippin’ Dots is celebrating their 20th anniversary by giving customers a free cup of their curious beads of ice cream from 4 p.m. to close today. Invented in 1988, Dippin’ Dots are touted as “scientifically advanced” due to their cryogenic-freezing process, earning them the title of “Ice Cream of the Future.” They are also releasing a new, yet unsurprising, flavor: Birthday Cake.

Unfortunately, the offer is only available at franchise stores; this excludes parks, stadiums, theaters, etc… No participating locations are found within D.C., but shops can be found in Pentagon City Fashion Centre, Tysons Corner Mall, Montgomery Mall, Westfield Shoppingtown, and Dulles Town Center.
