Levitating objects can spin, glide and collide together — no magnets or magic tricks required. Using steady streams of sound waves, engineers maneuvered hovering toothpicks, coffee granules and ...

A group of international researchers have developed a way to use sound to generate different ... while other patterns caused the objects to move along circular or spiral paths.” ...

First theorized in 1938, heat's wave-like flow through superfluids, known as "second sound", has proven difficult to directly ...

They also levitated a wooden toothpick — something that had never been done before — while rotating it and moving it forward and backward. Sound waves exert pressure when they hit a surface ...

The platforms emit sound waves which move upward until they reach surface lying above, where they bounce back. When the downward-moving reflected waves overlap with the upward-moving source waves ...

A plastic plate above the chessboard reflects the sound; if the sounds waves are strong enough, objects can hover and move around between the board and the plate. Daniele Foresti, also a ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation ...

When an earthquake creates sound waves that travel upward through the atmosphere, the upper parts of the waves move faster than the lower parts. This makes the wave front lean or tilt as it moves.

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...

Rather, it's transported through the air by molecules moving around, constantly colliding with each other and scattering in all directions as it diffuses outward. Sound, or acoustic waves ...

Semi-circular canals To help you balance. They play no part in hearing. How we hear: a sound wave is funnelled into the ear canal by the pinna the vibrations in the air make the eardrum vibrate ...
