What is acoustic levitation used for? – Magic Tricks With Cards

As well as being used to levitate small objects to a height of 100ft without causing them to crash, acoustic levitation is also used to enable more complex objects to be hoisted. For example, it can be used to lift a boat up to 25ft, by using a specially designed shock absorber.


Does it require a huge amount of acoustic energy?

The size of a small house is quite different from the size of a typical train carriage. When you use a large car, there might be a huge amount of room underneath the roof which is left as ‘air’ and is therefore more powerful. Also, the roof must be supported or ‘maintained’ from a heavy cable, which is a very large amount of force (usually, it’s more like a 10 Tonne cable).

So what the difference is between a house and a train carriage?

When a carriage is used for transport, the entire length of the rail is supported to ensure that it can be moved efficiently as a single unit. Of course, the air or air pressure between the tracks inside this carriage is constantly fluctuating, and it’s the same when you use the loudspeaker to lift a house, or hoist a bicycle. It’s a huge amount of force and energy, plus the fact that the air pressure between the rails inside the train carriage is much higher, and therefore it is possible to lift an elephant, but it’s a lot more difficult to lift a bicycle than a house. It takes much more space to lift the train carriage than the house does, since the air pressure between the rails is less.

Also, when you are using large carriages, such as the coach car or railway carriage that use air pressure in the carriages to lift, when they are loaded, all the air is forced into the centre of the carriages, which creates more energy than the same amount of air pushed by the loudspeaker. But this is a small amount of force, and only a very small amount of force.

Does it help to increase efficiency?

All in all, it doesn’t. A loudspeaker is not a very efficient device, mainly because of the large amount of energy it would require to move a large amount of air, without any help that’s usually provided by the air pressure inside the train carriage.

But it can make a big difference when it comes to lifting something from a deep sleep. The first time I used it, I got a little nervous because
