Fascinating, what ideas we humans can come up with.
The interior of an 18″ square x 1″ piece of Plexiglas was charged to 2.2 million volts (MV) using a 5 MV particle accelerator. A layer of excess electrons become trapped deep inside. When discharged, the excess charge escaped with a bright flash and a loud bang. The hot, lightning-like discharge created thousands of microscopic fractures inside the acrylic, resulting in a branching “Captured Lightning” sculpture (or Lichtenberg Figure).
With this special coin, nobody will be able to find your secrets. It looks and feels like a regular coin, but its hollow, and it exactly fits one micro SD card.
Once the card is inside, just place the other side of the coin on top and press shut. It comes with a special opening tool that you’re supposed to use to open the coin. Without this tool, you won’t be able to open it.
Also, it comes in a variety of different countries currency!
Pretty nifty, until you loose it, or accidentally buy something with it.
How could a square shaped wheel possibly be more efficient than a round one? That sounds ridiculous at first, but if you think about it, a square wheel would have less contact area with the ground. Not that a regular cube would be of much use as a wheel, this cube however has a special helix shape and the threads are in a sine-wave pattern which combined with the material reduces the surface area that makes contact with the ground, in turn reducing friction and speeding up rotation.
Skateboarder David Patrick’s crazy SharkWheel was discovered by chance while he was creating a cube out of six soft pieces of piping. Patrick dropped the cube by accident, and to his amazement, the piece started rolling and it didn’t stop.
