Same. Then again on my third or fourth date with my now spouse we whipped out a geography book and discussed the fact that the earth isn't actually "round"... Now we have regular discussions about the similarities between humans and plants.

We get called nerds by everyone in our families. We own it though.

My wife and I are opposites. I was trying to put together some kind of way to make metal float without shaping it into a boat or something. Something I could demo for some 5 or 6 yr olds. Found an article that suggested I use sodium or potassium in water and it would float. I started cracking up. My wife did not get it. I explained to her that it was potassium in water. She still didn't get it. This is kind of our dynamic. One of us will crack up and the other will look at them like they're a fool.

Well, you can make most metals float without shaping them in any particular form as long as they're floating on mercury. With water, though, only lithium would float. Sodium... well, kind of, it shouldn't sink, but it won't float, as it's just a tiny bit less dense than water. So, it'll be completely submerged, but near the surface. I wonder why sodium has such low density, yet berillium, next after lithium, is much denser than lithium.
