Why do Atomic Bombs make a "Mushroom" shaped cloud when they detonate? | [
"Hot air rises. When there is a large enough source of heat, it creates a column of hot air that is much hotter in the center than on the edges. The center of the column rises faster, causing the air around the edges to curl and create the mushroom shape. Then, with a big enough explosion the air eventually reaches... | [
"There is no difference between Atom Bomb or Nuclear Bomb, these terms refer to the same thing. There is a difference between a Fission bomb and a Fusion bomb (aka Hydrogen Bomb). The Hydrogen bomb is far more powerful."

Why do hackers feel the need to release private information to the public like officals' names and addresses? What do they gain from this? | [
"The same thing that kid in middle school got out of making fun of your shoes and squirting ketchup on them. Publicity and embarrassment. Bullies thrive off of the reaction they get out of it, my assumption is thats what pointless hackers get out of pointless hacking."
] | [
"Usually with companies that get breached, there is some company-consumer assurance that their data will always be safe. So when it is breached, its like a breach in their trust. It is also extremely difficult to find the hackers, they may be on the other side of the world. Thus, not being able to bring the suspect... | eli5_question_answer | {

Why fog lights are able to cut through fog while brights only light up the fog more. | [
"Fog lights are closer to the ground and are aimed slightly downward, so that only the fog very close to the road's surface reflects light back. High beams are high and have a wide beam that sends light upward, so that instead of just a thin layer of fog between you and the road being lit up just about everything i... | [
"Like you're five... The yellow light does not reflect off the water as readily as the blue in white light does. It more effectively cuts through the bad weather and shows you the road."

What is turbulence? And how do airplane pilots sometimes know when they are about to hit turbulence? | [
"Pilot here...Pilot reports are really the best way to know when it will be bumpy. One plane 100 miles ahead will report turbulence at a certain altitude to ATC and then they will relay the message to other planes. Those other planes can then decide if they want to deviate course or altitude...Also just don't fly i... | [
"Here I thought OP was literally asking about the plane. Planes change altitude by speeding up or slowing down, not by pitching the nose up or down as most everyone thinks. When the pilot is trying to get out of the turbulence, they may either turn to the left or right to get away from it, or speed up or slow down... | eli5_question_answer | {

How can any drug cost $360,000 a year for a patient. | [
"When a pharmaceutical company creates and patents a new drug, they can charge as much as they want for it, since no one else is able to sell or produce it without their consent.

Why are some foods high in sodium but they don't taste particularly salty? | [
"Not all sodium is in the form of salt (sodium chloride). Baking soda, for example, doesn't taste nearly as salty as the same amount as salt. MSG has sodium and isn't salty (though it's generally used in small quantities). Also, other tastes, especially sweetness, can hide the taste of salt."
] | [
"Some of the salt is replaced with potassium chloride which has a similar taste and the benefit of potassium which can be difficult to get in your diet. There might be other substitutions that I'm not aware of."

Are there any differences between Prison Labor and Slave Labor and should we worry about the future of privately owned prisons? I know Slavery is not entirely illegal according to the 13th Amendment. So it's kinda scary to imagine what could happen, am I worrying for no reason? | [
