A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand. 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. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. 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, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. According to Chaudhri and Chandrasekar, the shrapnel from the explosion flies through the air at speeds of up to 90 kilometres an hour.Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. The head can resist enormous loads, but if the tail is broken by applying the smallest pressure with finger and thumb, the drop explodes within a few millionths of a second with a sharp retort. Each drop consists of a long, thin tail attached to a head about a centimetre across. The drops form when blobs of molten glass are rapidly cooled, or “quenched”, in water. The extraordinary properties of Prince Rupert’s drops had been recognised in Germany some forty years earlier. Chandrasekar of Purdue University in West Lafayette, Indiana, have filled in the final piece in the 300-year-old puzzle (Philosophical Magazine B, vol 70, p 1195, 1994). A long waterfall pouring down from its edge, fed by a lake or stream that seemingly has a never-ending supply of the stuff. With the aid of high-speed photography, physicist Munawar Chaudhri of the University of Cambridge and materials scientist S. There’s a profound image of a beautiful land mass floating above the world, exhibiting its glory despite the powers of gravity, almost flaunting its specialness.
But if Prince Charles does ever ascend the throne, he will be one up on his famous ancestor. No one could give Charles Il a satisfactory explanation of the extraordinary behaviour of the glass teardrops. The drops are reliably reported to have been made in Mecklenburg (North Germany) at least as early as 1625. Most of the early scientific study of the drops was performed at the Royal Society.

two computers (referring others to Mozy gives free users an additional 0.25 GB of storage space). A scholarly account of the early history of Prince Rupert’s Drops is given in the Notes and Records of the Royal Society of London. Prince Rupert’s drops, as they are now known, had a quite remarkable property: they were immensely strong, able to withstand the weight of a 1-tonne wagon without shattering, but at the touch of a finger they exploded like a bomb. Wuala is a secure online storage, made in Switzerland. IN 1661, King Charles II asked his personal scientific society, later to become the Royal Society, why do teardrops explode? The teardrops he had in mind were the size of a fingernail and made of glass, and they had been brought to England by Prince Rupert of Bavaria.
