levitation

Scientists float boat upside down on a levitating fluid

Vibrating liquids at certain frequencies can cause objects to exhibit anti-gravity effects.

Physicists propose a new way to levitate and propel spacecraft-sized objects with light

The concept is audacious -- but it might be just crazy enough to work.

Sound levitation technology might one day replace laser surgery

Sounds like magic!

Thermal levitation can lift any object in the air, unlike other methods that work on magnetization or optical light

Large objects were levitated by exploiting temperature differences. This method works with any kind of object.

Engineers create first true sonic tractor beam

There's three things every good alien movie needs, in my opinion: aliens, spaceships and tractor beams; so far, science hasn't really delivered well on the "alien" part, and our spaceships still have a way to go. However, recent work in the UK might pull the third element out of the realm of sci-fi into reality.

Japan casts steel-like glass using levitation

Using a newly-developed production method, the Institute of Industrial Science at Tokyo University succeeded in producing a type of glass that rivals steel in hardness. The new material opens huge developmental lanes for any glass and glass-related product, from tableware to bulletproof glass.

Moving and levitating objects using sound waves

Water droplets, coffee granules, fragments of polystyrene and even a toothpick – all of these, and more, have been levitating and moving around in a Swiss laboratory lately; all of them lifted by sound waves, that is. This is the first time a device is capable of handling several objects simultaneously. This achievement was detailed […]
