Me at 8: "I'm going to be an astronaut when I grow up!"

Me, many decades later: "Oh, hell no."

@WKCosmo @skdh He's invented a new form of comedy.

@TSHamiltonAstro @radioactivered I tried to built the x-ray machine they showed plans for but my grade 8 teachers shut it down and confiscated all the parts. Took me weeks pulling apart old discarded TVs to find the list of supplies.

@TradeTexasBig I used to climb up to the top of that peak in the distance. Now that's a view.

[Greg Trayling @GregTrayling]

@TradeTexasBig I grew up close to there. If you like gardens, you might enjoy the conservatory dome atop Queen Elizabeth Park, built around an old quarry.

@NikoSarcevic Maybe because it happens often? I've seen it two or three times.

@pascalkwanten One minute, 9 billion people is good for you, the next it's not. I wish people could make up their minds.

@TSHamiltonAstro I've asked locals about the (almost) complete lack of AC in the UK wandering around and they say they just never needed it until recently. You'd expect they'd maybe have some Brit version called chilly fans with strange controls but many areas still have nothing.

@For_Film_Fans Someone ask him why the ball was ground up in the end, I never got that.

[Greg Trayling @GregTrayling]

@TSHamiltonAstro I never understood why it was ground up in the end. Nobody could answer that.

@fakehistoryhunt I have a similar game, called "Pdfs I Downloaded into a Folder".

And on top of that, one of his lab assistants, Francis Hawksbee, showed Netwon and a few others the eerie triboelectric discharge he found in a partial vacuum, along with other electrostatic demonstrations, and Newton didn't seem to pursue it. The vacuums did involve the use of mercury, so maybe he was misdirected into alchemy thinking that mercury was somehow the source?

@CburgesCliff @ironmoon44 @Science_George I grew up in the Rockies and get very disoriented without mountain peaks for directional reference, never realized how much I relied on it until moving to other places.

@CoffeeNGrit That's exactly the time I'd clumbsily knock all the foil pans onto the ground.

@carolemadge All those centuries, and it still looks dead straight and level.

@SpinVector @WKCosmo I started making finger quotes when I remind the class to fill out their "anonymous" surveys, which I'm sure they are, but my ratings shot up ever since.

[Greg Trayling @GregTrayling]

@SpinVector @WKCosmo How is it not anonymous if there are still 11 possible respondents? We don't know which ones constitute the set that's less than 5.

@peterrhague I heard the initial explosion hurled it into the air and propelled it halfway across the planet!
