Tractor Beams


It’s not just Star Trek, now.

Scientists have recently developed a real-life tractor beam. It has the ability to lift up objects and move them around, seemingly defying gravity. They are ultra-precise and function just like an invisible pair of tweezers. Scientists can move small objects up, down, left, right, and around. Maybe you’re thinking…

Nope. Can’t be real. He’s not even telling us HOW IT WORKS!

But I will. Scientists have always known sound waves have the ability to move objects around. One of the creators, Sriram Subramanian, said “In our device we manipulate objects in midair and seemingly defy gravity.” This is done by an array of 64 tiny speaker that create high-pitched and high-intensity sound waves that can hold a small ball.

Although these tractor beams cannot lift a human, the creators are hoping they can create one that can lift a large soccer ball from 35 ft. away. Hopefully, planes will eventually have tractor beams and they won’t even need to land, or some other thing like that. It would make life a lot easier.
