This is all about levitation. The background story is that you
invented a way to amplify your own telekenetic abilities so that
you can make things levitate with your mind, while wearing a
special glove attached to an eccentric-looking electronic machine.
"But one thing that's always bugged the design is that you can only
move one thing at a time. When I offered my services to people,
they say that's no problem, and they'd hire me for jobs like
lifting a piano up to the second story of a house. But nevertheless
the person upstairs would get very annoyed when they started
receiving each key from the keyboard individually. So now I present
it here purely for your visual amusement..."
First the glove itself does all the magic. The idea is to arrange
it with a bowl of ultrasonic transducers that are formed when you
close your hand up to a certain point fixed by a structure within
the glove. The glove will need to have a bit of a webbed aspect to
this, something like a baseball glove which you'll be wearing on
your other hand later. With this you can possibly pull of some
classic "ultrasonic accoustic levitation" tricks with really
tiny/light objects. Maybe add a wire mesh layer in the glove's
construction and stick in a small tesla coil to make some arcs.
Lift things off a table if possible.
This won't be all that impressive, but it sets the foundations for
the following step which is to ask the audience for anyone with a
solid metal ring (no jewels etc.) that you can levitate. Note
around this time that you've been toying with the power levels.
This time you use a trick built into the table. Also put on a
baseball glove to catch it in the air.
