Neodymium magnet ball video of a family of geometric forms all built from the same subunit, a reinforced tetrahedron.
The unit is made from 4 hexagon elements of 18 balls each, so each unit uses 72 balls, half golden and half nickel for the colour effect.
There's a mistake in the onscreen titles for the final and largest structure shown: it uses 65 units not 55, so a total of 65 × 72 = 4680 balls.
I'll leave you to do the math for the other shapes in the video.
Music track is Don't Leave Home by New Zealand electronica band Sola Rosa.
