How to Make Your Own Sliding Puzzle

As a kid, I loved sliding puzzles—moving tiles around to line up rows of numbers or reassemble a photo was an excellent brain-teaser. As these games became computerized, they seemed to lose a little of their magic; sure, you can click around to "slide" the pieces, but where's the fun in that?

In this vintage clip from Curiosity Show, we learn how to make your own physical sliding puzzle at home. (Incidentally, there are also plenty of sites devoted to digital ones online.) The only problem with this clip is that it relies on a Kodak slide box to contain the puzzle...and Kodak no longer makes slide film. Plus, even if they did, you probably don't have these boxes lying around. You'll want to figure out a decent substitute "shallow, square, box-like object" depending on what you've got around. In my house, a square tissue box (cut out so just the bottom bit remains) is a reasonable option, as are many boxes from electronics (the Apple Airport Extreme comes in a very sturdy square box).

Gather the kids around, figure out what you want to turn into a slide puzzle, and enjoy:

Watch an Antarctic Minke Whale Feed in a First-of-Its-Kind Video

New research from the World Wildlife Fund is giving us a rare glimpse into the world of the mysterious minke whale. The WWF worked with Australian Antarctic researchers to tag minke whales with cameras for the first time, watching where and how the animals feed.

The camera attaches to the whale's body with suction cups. In the case of the video below, the camera accidentally slid down the side of the minke whale's body, providing an unexpected look at the way its throat moves as it feeds.

Minke whales are one of the smallest baleen whales, but they're still pretty substantial animals, growing 30 to 35 feet long and weighing up to 20,000 pounds. Unlike other baleen whales, though, they're small enough to maneuver in tight spaces like within sea ice, a helpful adaptation for living in Antarctic waters. They feed by lunging through the sea, gulping huge amounts of water along with krill and small fish, and then filtering the mix through their baleen.

The WWF video shows just how quickly the minke can process this treat-laden water. The whale could lunge, process, and lunge again every 10 seconds. "He was like a Pac-Man continuously feeding," Ari Friedlaender, the lead scientist on the project, described in a press statement.

The video research, conducted under the International Whaling Commission's Southern Ocean Research Partnership, is part of WWF's efforts to protect critical feeding areas for whales in the region.

If that's not enough whale for you, you can also watch the full 13-minute research video below:
