Putting a large marshmallow gummy bear in a vacuum chamber

As the air leaves the chamber, the marshmallow gummy bear bloats. Its candy skin forms fissures. After it reaches its maximum size, the operator opens a valve. The bear implodes under atmospheric pressure, becoming a puddly lump at the bottom of the chamber. Read the rest

Video of cube passing through hole in equally sized cube

If you have two cubes of equal size, it's possible to cut a hole in one cube that's large enough for the other cube to pass through it.

From Wikipedia:

In geometry, Prince Rupert's cube (named after Prince Rupert of the Rhine) is the largest cube that can pass through a hole cut through a unit cube, i.e. through a cube whose sides have length 1, without splitting the cube into two pieces. Its side length is approximately 6% larger than that of the unit cube through which it passes. The problem of finding the largest square that lies entirely within a unit cube is closely related, and has the same solution.

The original proposition posed by Prince Rupert of the Rhine was that a cube could be passed through a hole made in another cube of the same size without splitting the cube into two pieces.

Spoiler: it went way better than Oregon's exploding whale...

PS: here's the "blowed up real good" reference if you're scratching your head.

Excellent USB microscope on sale for $30

I wrote about the terrific Plugable USB Handheld Digital Microscope in 2015. It's on sale for $29.70 right now.

I had the earlier version of the Plugable USB Handheld Digital Microscope and liked it a lot. The second version just came out and I love it. Smaller than a prescription pill bottle, the microscope has a USB cord that can be plugged into any computer. Download the software here and start looking up close at money, leaves, circuit boards, bugs, skin, hair, and anything else.

The scope has a built-in, adjustable-brightness LED for illumination. The brightest setting is not always the best - try different levels of illumination and let the software auto-adjust the contrast. I also learned that in order to see things at the maximum 250X magnification you need to follow the instructions in the FAQ.

The scope comes with a suction-cup gooseneck mount that is very stable, and a plastic board with a grid pattern, which helps you align and locate the thing you are looking at. You can also simply hold the scope against things. The software takes still photos and movies, and hasn't crashed on me yet (the earlier version was buggy).

At this price, the microscope is an amazingly entertaining device and I find myself grabbing it to check out all sorts of things, including splinters, skin cuts, bugs, and playing card designs.
