My nephew who just turned 5, as he kept informing everyone- "I'm a whole five years old!"- visited from Cali so Mom and I took him to the Science and Industry Museum.OK, I hadn't been there since I was a school kid and it was amazing, but that's not what this story is about. This story is about our tour of their coal mine.
David was very eager to go and when the guide told us we were 600 pretend feet underground we heard some "whoas" and "awesomes".
Later he was showing how the flame lantern miners used to check and see if there's methane down there basically turned them into walking bombs. But the flame things only cost $30 while the methane meters, invented in '62, cost $600--- "Which is how deep we are underground!" David exclaimed. That took us all a minute to process.
The point being the modern machinery is often prohibitively expensive. "Like this building-sized drill modern mines use, can anyone guess how much this costs?" Our wonderful, patient tour guide asked.
David goes, "Three... hundred... forty five.... million dollars!!!" He loves coming up with big numbers. "Did you just say three hundred forty five million dollars?" asks a very perplexed guide. "Yeah!" "Um, yeah, that... that's just about exactly what it costs..."
Gathering his thoughts he explained to us it had a section called a roof shield. "Knights used shields too actually," David informed him. "Yeah," the guide rolled with it, "and do you know what they used them for?" "Well, if an asteroid came down they could bounce them off the shield!"
By now I'm bent over double trying to stifle the lafinks and Superguide comes up with, "... yeah... and this one's also to protect from falling rocks."
David turns around and looks at her. "I'm gonna be a ninja."
^Someone asked about the wires. They're just 20 gauge brass. I was surprised to find I liked the 20 more than 22- it's sturdier in the ear hole, without being uncomfortable like 18 gauge.)
For some reason all visit long, he was explaining to us that "infinity is not a number, it's a concept." The final night something occurred to me.
"David, what's a concept?" I asked.
He threw his tiny arms up, "I don't know!"
And in case you think I only poop rainbows, here's a piece of crap I threw together out of really good bits that didn't work at all-->>
