Isaac, Joshua, and I are driving home. With about five minutes to go, we see the windmill at Dutch Village.
Isaac: how do windmills work?
Amanda: the wind turns the blades and that turns things to make power. Like in Sharp Cutter*, but with wind instead of water.
Isaac: ooh. Water wheels make power.
Joshua: I don't want to go on a water wheel. It's scary.
Isaac: so water, and sun, and wind and there was one more.
Joshua: I don't want to go on a water wheel. It's scary.
Isaac: water, sun, wind and what was the other one?
Joshua: I don't want to go on a water wheel. It's scary.
Amanda: ok Joshua, you don't have to go on a water wheel.
Isaac: what is another kind of power?
Joshua: I don't want to go on a water turner.
Amanda: well, there's coal and nuclear and biomass and...
Joshua: I don't want to go on a water turner. It's scary.
Amanda: ok, you don't have to go on a water turner.
Joshua: and not Isaac.
Amanda: no, Isaac either.
Joshua: and not Dad
Amanda: no, not Dad either
Isaac: hmm. wind, sun, water and one more
Joshua: and not mom
Amanda: no, not Mom either
Joshua: and not Bear.
Isaac: oh, I know!
Joshua: and not Bear.
Isaac: pumping power!
Joshua: and not Bear.
Amanda: and not Bear.
Amanda: what's pumping power?
Isaac: it's with your legs. Like running.
Amanda: hmm. Well, if you ride a bike you only get about enough power for a light bulb. So it's not the best way to get energy.
Joshua: I don't want to go on a water wheel. It's scary.
Isaac: but you could run.
Amanda: sure, you could run.
Amanda: Joshua, you don't have to go on a water wheel.
...and on and on and on...
