Spinning Tops: Video to Soothe You

In this seven-minute film by Charles and Ray Eames, we see spinning tops from around the world. It's stunning seeing the variety of tops that are out there -- many use wound-up string to start, others use a pumping mechanism, and others do amazing things like break into multiple independently spinning bits. And yes, there's a whole segment on different styles of dreidel.

If you're sick and tired of storms and elections and hyperactive internet videos, jump in my 1969 time machine and enjoy this mellow-but-engaging look at the simple beauty of toys.

If you like this video, there's five more hours on the massive Films of Charles & Ray Eames collection.

Knock-Off Versions of Nerf Ammo Can Cause Serious Eye Injuries

Nerf toy guns and their foam projectiles, as marketed and manufactured by Hasbro, are virtually harmless when used as instructed. But, as reported by CNN, a recent paper in the UK medical journal BMJ Case Reports is providing a reality check when it comes to using the mock weapons and off-brand ammo improperly.

Three unrelated patients were treated at Moorfields Eye Hospital in London with ocular injuries that were sustained as a result of being "shot" with Nerf guns. Two adults had bleeding and inflammation in the eye; one 11-year-old had bleeding, inflammation, and damage to the outer retinal layer. All three suffered what the paper described as "significant ocular trauma." Attending doctors treated their swelling, and all symptoms resolved within a few weeks.

So what happened? In the case of one patient, a Nerf play session went awry as a result of using non-licensed ammo that isn't subject to Hasbro's quality control measures and may be made of harder materials as a result. On their Nerf landing page, Hasbro cautions users to "never modify any Nerf blasters or other Nerf products. Use only the darts, water, rounds, and discs designed for specific Nerf blasters."

Pediatric ophthalmologists interviewed by CNN recommend that protective eyewear be used whenever anyone is playing with Nerf weapons. It's also advisable never to aim for the face when shooting and to avoid attempting to modify the weapons to shoot faster or farther.

Watch Craftsmen Shape Gobs of Molten Glass into Colorful Marbles

Marbles aren't just for schoolchildren. Humans have likely been playing with the tiny toys for thousands of years, as indicated by ancient Egyptian artifacts and other objects studied by archaeologists. These trinkets have been crafted from materials including clay, stone, wood, glass, and metal. But in the early 1900s, Akron, Ohio–based Martin F. Christensen changed the way the playthings are made when he invented an automated machine that produced glass marbles.

Christensen's machine ultimately paved the way for the mass production of marbles. But in the video below, you can see how they're made the old-fashioned way. Produced by The Magic of Making—a series of short educational films created along with BBC—and spotted by The Kid Should See This, the clip shows glass makers in action as they use large ovens to melt granules of sand into liquid, and as they stretch, twist, and shape the molten goo into fragile (yet still playable) creations.
