Liquid oxygen is magnetic. O₂ has two unpaired electrons, so when it liquefies, those spins line up and the fluid is paramagnetic, it gets pulled into a magnet. A cryogenic liquid behaving like a metal? Quantum mechanics on display.

A bar magnet has a magnetic field around it. The magnetic field around a bar magnet flows from the north pole to the south pole and is strongest at the poles. ✍️

This mesmerizing phenomenon occurs because liquid oxygen is highly paramagnetic (attracted to magnets), and it boils at an incredibly low temperature, roughly 200°C colder than room temperature. This massive temperature difference triggers the Leidenfrost effect, where the liquid oxygen instantly vaporizes upon contact with a warmer surface, creating a protective cushion of gas that allows the droplet to "dance" or skate across the surface without friction.

Copper itself is not magnetic. However, the magnetic field causes electrons on the surface of the copper to rearrange themselves and begin rotating. This is the interaction of a magnet and copper. [📹styro.drake]

Last week we successfully ran hot liquid metal over a wall (under vacuum) and circulated it in a loop for 100 hours straight. This is a major engineering milestone and a significant step toward liquid metal walls in our future devices. #shiny

Aluminum isn’t magnetic. Yet spin it over a magnet and it lifts. Moving fields stir electric currents inside the metal, and Lenz’s law says those currents must oppose whatever created them. The metal pushes off its own reflection. Stop the spin and it falls. Motion is the rent.

This is how I make a Liquid Glass button with @Framer's AI Agent. Steal it! 1. Asked the agent to build a liquid glass background + a WebGL chromatic metal shader 2. Layered them and tuned till it felt right Prompts below 👇

Neutron is a reusable medium-lift rocket developed by Rocket Lab for launching large payloads into space. It is powered by nine Archimedes engines on the first stage and a single vacuum-optimized Archimedes engine on the second stage, using liquid methane and oxygen. It can carry up to 13,000 kilograms to low Earth orbit, making it suitable for satellite deployment and future space missions.

Liquid Glass has landed on Cosmos iOS. The bottom navigation is always shapeshifting, so it felt like the perfect place to introduce it. Currently experimenting with more ways to integrate glass into Cosmos universe. Maybe even a little drip from the Dynamic Island.. 👀

The Liquid hack negotiation is happening in OP_RETURN. So I turned it into a chat app. Live, PGP-verified, with shared reactions, and a slot for the attacker's private key whenever he drops it.

This woman is doing her own maintenance on her car by filling up her own windshield washer fluid and proudly declares that she doesn’t need a man.after she does this she notices her car is behaving strangely and takes it into the shop, when they drain her oil in the engine, the liquid that comes out is running blue. Should this woman hold off on giving up on men just yet, or should she at least learn how to look up how to do things first before she ruins her car and other things?

Helium is cooled to just above absolute zero & becomes superfluid, a zero-viscosity quantum liquid. It has no internal friction, climbs walls, seeps through microscopic pores & forms ultra-thin films. “Real matter is really like quantum material, obscured by room temperature…”
