You should've listened to Dr. Bentz, because organic chem is so cool. :) The "charged end" bit is polarity, and as it turns out, water's actually...
For extra fun, make it six jars, and quartz (that transmits ultraviolet), not glass. Put all six in a climate-controlled room. Put a strong UV...
Yep. But we're living in the future, and I'm describing a futuristic annoyance.
This. I'd love to see platinum at $50/oz, because I'd be stocking up on labware. Super-high melting point, malleable enough to shape into useful...
It looks like a bot run amok. I've reported it; maybe others should too.
Is there a "worst answer" option? Acetone does not "deteriorate the finish". Rubbing with toothpaste will absolutely leave hairlines on the...

Try shining a bright light across the surface at a low angle. That will highlight any relief that's left. It may just be flat at this point, though.
Those cents look like they were in a fire for sure. Nice find indeed on the SLQ! It looks like you might almost be able to make out the date...

Looks like it was polished and then stood on edge with a blue wall behind the photographer...
What do traders say about betting in either direction on a market where you have insufficient information?
Now, that's just silly. I think there's a really good chance that, at some point in the future, one bitcoin won't even cover a cup of coffee. I...
When you're grading the coin "in hand", are you allowed to put your thumb over the biggest hit? :rolleyes:
So, why, given that re-submission carries the chance of an upgrade? Does the grading fee impose enough friction to prevent this from running out...
It doesn't much matter whether TPGs overgrade coins "all the time" or "almost never". As long as there's a chance for a coin to end up in a slab a...
That was my first thought, too, but I think beer bottle caps are bigger in diameter...?
But saying virtual currency is "something an inventive coder can create from scratch" is like saying that greenbacks are something an inventive...
But the dollar had ten or more times its current value at the time these bills were used. So, why not reinstate $1000 bills, so you can (as in...
But such coins aren't missing the nickel, they're missing the clad layer -- which is a layer of alloy that's 25% nickel, 75% copper. Yes, they...
