From the Ri Channel's View the Tales from the Prep Room series, this is how you make a fluidized bed of sand: Making Sand Swim. Watch how these solids suddenly behave a lot like a fluid as air escapes between the sand particles, causing them to float. It’s definitely one of the more strange and fascinating demonstrations that we’ve seen.

The New York Times’ video profile of Max Mulhern’s “Aqua Dice” shows how the artist’s love for the sea and his interest in unknown outcomes came together into one project.

Fate adrift, these two giant sea dice were constructed out of plywood, pine, PVC and epoxy. Technically illegal — “you’re not allowed to put an object on the water that’s unattended, and you’re not allowed to go to sea if there’s not a constant watch on-board,” explains Mulhern, — they are designed to collapse on impact so as not to be a danger to any other vessels, and are brightly painted. They also have GPS in both of them, customized by technology students, to track where ocean currents are taking the dice and how far apart they are from each other.

“I’ve spoken to a lot of ocean scientists and they’re thinking that the dice will separate quickly,” he said. “What I like about that is the dual possibilities: there’s one throw and two outcomes, two possible destinations — and destinies.”

Whether you love art, love sailing or love the unknown, you can track the dice (and even bet as to where they’ll eventually land) on Mulhern’s site, on this map, or follow the journey on Facebook.
