Researchers create an optical tractor beam that pulls macroscopic objects

Researchers have developed a way to use laser light to pull a macroscopic object. Although microscopic optical tractor beams have been demonstrated before, this is one of the first times that laser pulling has been used on larger objects.

When it is irradiated with laser light, the pendulum turns toward the light.
