Two poles of different lengths balanced simultaneously on the head, as well as some other balancing tricks. This is know as a dual or twin inverted pendulum in control systems engineering. In the first 2 clips I use a long pole that is 4 times the length of the short pole. In the 3rd clip the long pole is only 3 times as long and is more difficult. The poles fit together in sections so that I can pack them in my bag. They're made from a cheap Argos wardrobe. The ball on the end of the long pole is mainly there to make the end more visible. I'm using rubber chair leg feet at the bottom end of the poles.
