Another fun experiment that will take some wonder out of the "but how did so many civs arrive at a pyramid?!"

Take a square box and put it in a sandbox, and then overload with sand it until the scoops just run down the side and no longer "stack"... voila... you've just made a pyramid! lol

Right.

The Italians couldn't get their hands on enough chocolate during World War II so they bulked it out with hazelnuts. A couple changes to the recipe two decades later and we have Nutella.

Actually you've got it backwards. Surface tension is going to pull an isolated cell into a circle as it minimizes length. Of the cell walls. When the circular cells are adjacent. The hexagon shape minimizes the length of the cell walls for adjacent cells

Well, adults can get any cereal they want, and while honeycomb is kinda nice, is it really the one you choose when you get to have anything you want?

Its the "kids consolation prize cereal" when your nutritionally responsible mom wont get the terrible-for-you sugary one you really wanted.

If they're in our orbit and orbiting the sun at the same rate, there's no chance of them hitting us. We keep the same distance apart at all times. It's asteroids crossing our orbit that have a chance to hit us.

But it's not actually in the exact same orbit. It moves around a Lagrange point where the Earth-Sun gravity interaction creates a stable zone to hang out with us while we move around the Sun.

Good observation! So it's not surface tension as claimed in the article. If it was only surface tension, I think isolated circular tubes would solidify into a hexagon as well.

I notice a lot of research papers exagerate their findings, and in some cases are just plain wrong, some fraudulently so (see Alzheimer's research scandal).
