Someone made my old school on Minecraft. The detail is incredible
This is honestly one of the best videos I’ve ever seen. Must have taken so long.
“As breathtaking as large, panoramic photos often are, the process of creating them is, to many photographers, a much less attractive prospect. While painstakingly stitching together images from a recent vacation, Technische Universität Berlin graduate Jonas Pfeil came up with a better idea: a spherical camera, called a camera-ball, that can take 360-degree panoramas in a single snap. Once the softball-sized sphere is tossed into the air, a built-in accelerometer tells when the ball has reached its zenith. Then a microcontroller triggers simultaneous action by 36 two-megapixel cellphone cameras, capturing a mosaic of images.”
Floating Water Bridge
Known as the water thread experiment, this phenomenon shown above seems to defy the intuitive laws of everyday physics. The experiment was first demonstrated in 1863 by British Engineer William Armstrong.
Two containers of deionized water, placed in some sort of insulator (glass beakers work fine), must be connected by a thin thread and exposed to a high-voltage charge (one beaker receives the positive charge, and the negative to the other.) At a critical voltage threshold, a water bridge forms between the two containers across the thread - which remains even when the containers are separated!
Typically, the diameter of this bridge is no more than 1-3 mm, but can remain intact as far as an 25mm! The surface temperature, due to the voltage, rises from about 20 °C (68 °F) up to 60 °C(140 °F)! The longest that the phenomenon has lasted is 45 minutes.
