For some reason, I always get choked up when he says, "Such high temperatures are common in nature. Where? In the insides of the stars." Carl's just that good, I guess

How do we know hydrogen is in there? Has anyone opened it up and lit a match to check? It could just be an empty bottle.

"All 92 of them" awwww how cute.

[slashingraven]

@devotedpupa By 92 he means the 92 elements that can be naturally found on Earth. He acknowledges the even heavier elements beyond uranium that were made in laboratories around 8:26.

My brain hurts, I love it!

Its like the keyboard that you type on is made of these particles moving at incredible speed to create a solid mass.

I love how he uses the tongs to pick up the Uranium.

[kurtjk01]

@GammyGoose Because he didn't want to end up like Marie Curie . . . Nobody picks up uranium bare-handed. At least no one who knows what it is does.

Man, is that really how the periodic table was arranged in the 80s or is that just a special table for the show? If the table really was organized in such a fashion I really feel bad for them!

[DrZenith]

Don't worry! They've just been arranged one after the other instead of in groups and periods that's all..

[fleebenworth]

Yes....I'm aware

[SaganAppreciationSoc]

Those uranium atoms look pretty irregular. WTF?
