So, we went to the Albuquerque Balloon Museum, and it was interesting to see all the hot air balloon stuff. But what caught my eye, as well as Eli's, was the helicopter making exhibit, where you could make little helicopters out of paper or paper cups. I made two, or should I say invented two, and Eli liked them a lot. He actually wanted to make some exactly like mine, but kept getting frustrated with himself. I was trying to teach him that everyone can make different ones, and they don't have to be exactly like mine to be awesome.

What I didn't tell him was that the fan they had for you to test out your helicopter with was so crappy that, in order to fly, they did have to be at least as good as mine, physics-wise. He didn't listen to me anyway, and gave up to go fly a hot air balloon simulator.

I was proud that the finer blade one would actually take off from the screen over the fan if you set it there. The other one has potential, but it will only fly if you hold it up a little higher. Both tip over within 6 or so seconds... not that great. But seriously, I can blow harder than this fan, so it was still an accomplishment. If you look close, I incorporated Bernoulli's famous shape into each blade. Good times, probably more time than I should have spent
