How do they know if it’s balanced or not? Would they need do the math manually?

It’s just one equilateral triangle and then two pairs. The specific slots the opposing pairs are in don’t matter. You can see that each sample of the triangle has a gap of 7 slots between each other.

How neat! Thanks for explaining in a simple and easy to understand way for those of us who aren’t in the know. I appreciate it!

Thanks, that’s a great explanation! I can see the geometry clearly once you mentioned the equilateral triangle :)

There isn’t much math to do really. Take as axioms that the obvious way to balance 2 or 3 tubes is in fact balanced, and that if you add a balanced arrangement of tubes to an already balanced arrangement, the result is still balanced.

You just fucking send it and see if it stays on the table.
