But, to be a little less florid and more sciencey, scientists have found an extremely unusual form of a crystal called icosahedrite, which had previously only been found in a weird meteorite or created in the lab. The difference here is that this specimen was found in a mineral made when the intense heat and pressure from the very first atomic bomb detonation — the Trinity test — fused the sand underneath it into glass. And not just the sand, but the metal from the tower it was mounted on and the copper from transmission wires connecting instruments to the test.
All of this came together to form a weird mineral called trinitite. It’s usually glassy and green, and, unsurprisingly, is slightly radioactive. A more rare form of trinitite is red, and a piece of this was found after World War II north of the 80-meter-wide crater from the test in Alamogordo, NM. The color may be due to copper oxide from the transmission wires fused into the mineral.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
