made especially for the beach, ‘screw cup’ by south korean, barcelona-based designer minji jung does what its name suggests. by turning the mug just like a screw, the device can be secured into the sand. a practical solution for sandy and windy conditions at the beach, when dug into the ground the cup has two advantages: liquid isn’t spilt over the side and the drink is kept cool even on hot summer days. made from ceramic, the quirky piece solves that ever-annoying dilemma of warm liquid just when you need to be rehydrated the most.

  • This product is full of whimsical fun, but its use case scenario may need some more thought. It looks like it would be unstable on a hard surface (off-level, narrow base; high centre of gravity, etc.) but it’s so close to the sand’s surface that stray grains kicked up by even the slightest wind, or the most careful of passersby would easily find their way into the mug. The insulating properties given by the interaction with the sand are a clever bonus, but I think this clever mug needs an equally clever lid.

  • Looks good, but there´s one big problem. Everytime you want to drink from that cup, you´ll have to un-screw it. If you pull it out straight, you´ll destroy the inner sand screwed shape. A simple cone will do the job without all the screw and un-screw process over and over. But that´s just my opinion.
