A, yes, quick sand, the bane of my childhood.

Reading all these adventure books and comics made me really fear quicksand as a child... I was living in East Berlins suburbs. The most comparable thing to quicksand would have been a mud puddle!

When I was a kid there was a Norwegian children movie called "The hunt for the kidney stone" where a kid travels into the body of his sick grandpa to find out what's wrong with him (kidney stone). After the movie I asked my mom what kidney stones are, and where they come from. "You can get them if you eat too much salt, for example" she says, and after that I was TERRIFIED every time my parents would put salt on anything.

Sometimes I look at the wide open sky and think "What if gravity suddenly reverses and I fall up into the sky and then space? That would be really dangerous."

Don't forget quicksand... I spent all my childhood afraid of falling into it. Somehow it was an unwarranted concern.

Roaming black holes

I remember freaking out when the last season of Friends aired - what, there are people vacationing in Bermuda? Are they insane? I was in my late teens

My uncle told me he sailed through the Bermuda Triangle all the time. I thought he was full of crap.

I was always worried about perfectly round holes in the ground and falling into them. Looney Tunes really over-represented how common they were.

Chubbyemu made me fear gas station sushi.

Watched a childrens show that showed a snakebite. Was unable to enter my bed for years without searching it for snakes throughoutly.

Every time i was somewhere where i could see a big fall, i would get scared, thinking i would intentionally go there and fall to my death without noticing

It's even funnier when you remember that like 99% of all matter is empty space, and electrostatic force is what keeps everything from sliding past everything else.

Neutrinos: tf is an atom I’ve never seen one

Fun fact: The Bermuda Triangle actually lives in your closet and plans to get you in your sleep.

Just as a reminder that even if you turned an entire atom into pure kenitic energy, you wouldn't even see a flash.

Math stuff:

So E = M c^2

I'll choose a carbon atom because it's a round number (don't think about that statement too hard)

So carbon has an atomic mass of 12 atomic mass units. In grams (divide by Avagadro's number) is 1.992 E-23 grams.

Shove that into E=mc^2 and you get 1.790 nanojoules, which is 4.974 E-16 kilowatt-hours. Or at 12¢ per KWH is 5*E-15 cents of power.

So to power a 500 watt gaming rig, you'd need to burn about 20 nanograms of carbon at 100% efficiency, per hour.

Just stick to elements lighter than iron and you'll be fine.
