On your table there are three transparent tubes, each about 10.25 inches (26cm high), which have a small, stable base. In the center tube there are three large yellow balls, about 2 inches (6cm) in diameter, that are clearly visible from a distance. One ball is put in each of the tubes. The two outer tubes are covered with elegantly decorated, red/silver sleeves.
The balls migrate from the left to the right tube, then from the right to the left, and back again. At the end of the first sequence all three balls are in the center tube – as they were at the beginning.
The balls are again put into each tube, and they penetrate the closed bases at the ends of the tubes when they are stacked on top of one another. The climax is reached when the magician makes two balls disappear and immediately finds them again together with the third ball in the center tube.
You can, of course, show the sleeves empty from time to time and at the end.
You could say that Giant Telesphere is a large scale cup routine with transparent tubes. But it is visible from a distance, can be performed in front of a small audience and while surrounded, and requires absolutely no sleight of hand.
