For most, this experiment is nothing new or special, but many don’t know that the iodine test is used to test for the presence of starch. It’s a simple, yet fascinating experiment, where starch turns into an intense “blue-black” color upon adding aqueous solutions of the triiodide anion, due to the formation of an intermolecular charge-transfer complex. Without the presence starch, the brown color of the aqueous solution remains. This interaction between starch and triiodide is also the basis for iodometry.

The McDonnell Douglas AV-8B Harrier II is a single-engine ground-attack aircraft capable of vertical or short takeoff and landing (V/STOL). It’s primarily employed on light attack or multi-role missions, and used by the United States Marine Corps (USMC), the Spanish Navy, and the Italian Navy. This second-generation Harrier Jump Jet are expected to be replaced by the Lockheed Martin F-35B Lightning II some time during 2025.

This scene appears to be straight from a movie, but it’s real, and a host of drivers were all parked alongside highway I-285 on Tuesday evening in metro Atlanta trying to grab as much cash as they can. Dunwoody police Sgt. Robert Parsons said the armored car crew estimated the loss to be around $175,000, when the vehicle’s side door accidentally swung open. The drivers may have felt lucky initially, but now some are slowly returning the money to avoid any possible criminal charges. Read more for the footage and additional information,
The Pyraminx is basically a regular tetrahedron puzzle in the style of Rubik’s Cube, divided into 4 axial pieces, 6 edge pieces, and 4 trivial tips that can be twisted along its cuts to permute its pieces. Just like it’s cube counterpart, the goal is to scramble the colors, and then restore them to their original configuration. Chinmay Prabhu, a 20-year-old from India, managed to achieve the record title for the Most Pyraminx (Rubik’s Cubes) solved underwater and all in a single breath. How did he prepare for this record setting run? He’s been solving Rubik’s cube puzzles since 2015. Read more for the video and additional information.
It’s not everyday that you see a Plymouth Hemi Cuda, much less one pit against a motorcycle, but that’s exactly what went down at a local dragstrip. A standard 1970 Hemi Cuda is powered by a 7.0-liter Hemi V8 engine generating 425 horsepower and 490 pound-feet of torque, but this green monster boasts a supercharged and / or NOS version that’s producing 925 horsepower. Is it enough to beat a modified Suzuki GSX-R1000? Well, the 500-pound bike does make 157 hp and 77 Nm of torque. Read more for the video and additional information.
National de la Recherche Scientifique (INRS) and CalTech researchers have developed T-CUP, the world’s fastest camera, and it’s capable of capturing ten trillion (1013) frames per second (fps), thus making it possible to literally freeze time to see phenomena – and even light – in extremely slow motion. The Slow Mo Guys met up with postdoctoral scholar Peng Wang to capture the speed of light at 10 trillion frames per second, so they diluted the water with a small amount of milk, in which the camera then records the beam of light as it travels across a few millimeters of that diluted milk.

We may not live to visit the galactic center of the Milky Way Galaxy, but thanks to data collected by the Chandra X-ray observatory, this ultra-high-definition visualization should definitely whet your appetite. NASA’s Ames supercomputer was used to render the data as a virtualization you can experience straight from your web browser. “This visualization shows the effects of massive stellar giants blowing off powerful winds in the region around the Galaxy’s supermassive black hole,” said NASA.

You’re not looking at computer-generated imagery, but rather Rose of Jericho, a desert plant that opens when moisture is present and closes up as if dead during short or long dry spells. In other words, it would be perfect for a Max Mad-like environment because it’s capable of surviving several years of drought, and even lose up to 95% of its water without being damaged and come back to life after exposure to moisture. Read more for a TED Talks video about these resurrection plants and additional information.
An opal miner from Queensland, Australia recently captured the process of exposing one of these incredible minerals, or the hydrated amorphous form of silica in technical speak, on camera. Boulder opal basically consists of concretions and fracture fillings in a dark siliceous ironstone matrix, with it found sporadically in western Queensland, from Kynuna in the north, to Yowah and Koroit in the south.

SeaWorld San Diego has just posted a fascinating time-lapse video of a Japanese spider crab shedding its old shell, and despite the clip being just 25-seconds long, the actual process took over six hours and enables the animal to eat more as well as grow larger. “It’s a perfectly natural occurrence for a spider crab. But for us as marine scientists to be able to witness Mother Nature in action in such an impressive way, that’s a great day at SeaWorld,” said aquarium curator Mike Price. Read more to watch.
