Does electricity need a high voltage or a high current to continue through a gap in a wire?

Say with a 0.5 mm gap would it be possible for me to get electricity consistently jumping across without dealing with a deadly current?

You need high voltage. Air is a very poor conductor, but by providing the electrons with a high voltage, they have sufficient energy to ionize the air between the two ends of the wire and create a conductive channel.

At standard temperature and pressure, you'd need 3 kV per mm of distance, so in your case, you would need to apply at least 1500 V in order for the gap to be bridged.
