This looks like science fiction. A phased ultrasonic array... creates moving pressure points in mid-air at speeds up to 9 m/s with full 360° freedom. LEDs track the acoustic focus, turning invisible sound into floating 3D images. Holograms made from physics, not screens.show more

Bernoulli’s Equation: P + ½ρv² + ρgh = constant... Mind-bending science that looks like pure sorcery! A lightweight paper loop floats and dances in a high-velocity air stream, seemingly defying gravity. Fast-moving air over and around the loop creates a low-pressure zone above and along its curved surfaces. Higher atmospheric pressure underneath pushes it upward, trapping it in the airstream. The Coanda Effect makes the air hug the curve of the loop, keeping the airflow attached and giving it remarkable stability. Gravity pulls down, while the pressure difference lifts up — creating a beautiful dynamic equilibrium. With nothing but moving air molecules, you can guide the loop wherever you want. Invisible forces at work!show more

Bernoulli's Principle states that "fast moving fluid creates low... pressure". The guy created low pressure outside with the water and air moves from high pressure to low pressure so it quickly sucked out the air from the room which creates deficiency of oxygen in the room and fire went out.show more

China’s Space Station Floating in Mid-Air Using Holographic Technology!... A high-speed array of holographic fans uses the persistence of vision principle to project a 3D image of the Tiangong Space Station and Earth in mid-air, without the need for special glasses. “Clearer than a fan and cooler than a TV!”show more

In the Russian science festival demo (likely the 2014... All-Russian Festival of Science), transducers created standing sound waves that trapped a rock in a pressure node, making it float stably midair by balancing acoustic radiation pressure against gravity.show more

Huawei's new 3D lock screen wallpaper is actually pretty... interesting. Unlike iPhone's Spatial Photo, which creates a fixed stereoscopic depth effect from a photo, this lets you scan an object 360°, generate a full 3D Gaussian Splatting asset, and use that as your lock screen. Tilt the phone and you're moving through a reconstructed 3D scene, not a fixed stereo image. The part worth paying attention to: 3D capture moving out of creative pipelines and into everyday phone personalization. That's a different kind of adoption curve.show more

That’s insane! 🤯 A student built an acoustic levitation... divide with an Arduino board. He built it using an Arduino Nano, a motor driver, and 60 ultrasonic transducers that can levitate low-density objects in place indefinitely. The transducers send out 40 kHz waves that create standing waves. The interference pattern produces nulls that trap objects. High-pressure areas form below and above the object, locking it in the low-pressure area between them. The transducers produce two sound waves moving in opposing directions at the same frequency and amplitude. The effect is that the low-pressure areas don't appear to move, like whipping a rope from both ends and having the wave meet in the middle. Sound waves are oscillating at high and low pressures. By creating a sound wave that doesn't move forward (a standing wave), you create areas of constant pressure. 🔉 Objects get trapped in the null points between high-pressure zones. The craziest part is that this was made more than 7 years ago! DIY levitation 😮‍💨 Reddit link: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →show more
