graceful revolutions
These ballet dancers are spinning tops made by the Canadian manufacturer foreverspin. All have identical size (3.55 cm tall, 2.8 cm diameter) and shape, thus the individual mass varies with the density of the used metal. These dancers were made from aluminum (Al, ρ = 2.7 g/cm3), zirconium (Zr, ρ = 6.52 g/cm3) and humanium (Hu, ρ = 7.94 g/cm3), respectively. Therefore Humanium has the best stamina for spinning and transmits the strongest impulse on its peers.
Snapshots of their performances are shown in the gallery.

Below are four short videos each of them is showing one model who is performing three movements. Of course, like the spinning tops, all figures in one set have identical size and shape but are supposed to have identical weight as well. However, the models may appear transparent in the GROK animated photographs. Pause/Play the videos by (un)hovering the mouse.
