Tractor beams!

They're not just science fiction anymore, apparently.

Using this technique and 40kHz ultrasonic waves (similar to a pitch that only bats can hear), they were able to levitate a two-centimeter polystyrene sphere, the largest object ever trapped in a real world tractor beam.

There aren't any tractor beams in the Wheel of Fire, but maybe I'll use them in a future work.  For now, my readers will just have to settle for sword-wielding assassin-monks, plasma rifles, space marines, anti-gravity engines, metaphysical planes of existence, and genetically engineered humans.  :D
