Secretagentpeptidebond - Mostly Harmless.

In this video, mixtures of inks (likely printer toners) and fluids move and swirl. Magnetic fields contort the ferrofluidic ink and make it dance, while less viscous fluids spread into their surroundings via finger-like protuberances. (Video credit and submission: Antoine Delach)

Wind tunnel testing plays a major role in the planning of many space missions. Here a model of the Mars Sample Return Orbiter is tested at Mach 10 to determine the heat shield’s response to aerobraking off Mars’ atmosphere. The colors are the result of electron beam fluorescence, in which an electron gun is used to ionize molecules in the flow, which causes them to emit photons (light). The technique can be used for flow visualization–as in the case of the shock waves shown here–or to measure flow characteristics like density, temperature, and velocity.

I originally started making this material not necessarily for armors but more for cars and trains. [I wanted it] to squeeze like a sponge, but in a heavy duty kind of form of a sponge so we could put it in front of the car or a high speed train and take care of the impact. But when we saw the performance of the material, we started thinking about ballistics and bullets. And so I tested those and we saw that…the material can perform.

Afsaneh Rabiei. He developed a metal foam that is lightweight, strong, heat- and radiation-resistant, and, when incorporated in a bulletproof vest, for example, capable of shattering bullets on impact without injuring the person wearing it.

That one time my roommate couldn't watch Shane's Asagao Academy stream so I live-texted it to her instead.
