why can a light tap or flick or what have you on my testicles hurt pretty bad, but ball-slapping sex doesn't hurt at all? | [
"Well, during ball slapping sex, things hurt less. Hormones, adrenaline, etc. For me at least, it's common for them to be a bit sore after."
] | [
"Yes. Though it is specific - hitting yourself in the balls will eventually make your balls less sensitive to hits, though it won't make boiling water on your hand less painful."

Why does standing up while drinking make it seem to hit us harder. | [
"I am no expert but it is because you are not using your legs/balance and when you sit and when you stand up it causes you to use these functions and since you were not using them before you did not notice them but when you stand up you realize you are intoxicated because it affects them."
] | [
"It is WAY easier to drink liquor when you're already drunk, which tends to lead to getting way too drunk and vomiting. Drinking beer hits you much slower, so its easier to gauge how drunk you are even after drinking liquor."

Picking the strings of a guitar while the other finger is resting on a fret doesn't produce a sound, except for certain frets like the 12th. Why? | [
"I believe why you're describing are harmonics. The 12 fret is special because it divides the string in half, that's producing sound when played. How it works beyond that is beyond me. You can also find natural harmonics on the 2nd, 5th, 7th, and 15th frets. In addition, you can create more harmonics by pressing ... | [
"1) Pressing a valve on a brass instrument makes the tube longer and lowers the note; this makes it easy to think in terms of flats. For guitar, moving up a fret shortens the vibrating string, creating a higher note, so it's easy to think in terms of sharps. 2) You can tune a guitar however you want; but all your c... | eli5_question_answer | {

What is the white foam that forms on top of the water when you cook pasta ? | [
"It's starch. By the way, when cooking pasta, or any starchy items, add some oil to water. Note that this is NOT for the folk tale of making the pasta \"not stick\", it doesn't do jack for that. But it will prevent the pot from boiling over."

Why is circumcision not viewed as genital mutilation? | [
"Because circumcision is seen as \"normal\" in your particular culture but other forms of genital mutilation are not."

"Sometimes it's medically necessary due to phimosis, which by definition can only happen to *adult* men. Circumcising infants? Unnecessary and possibly harmful.

How card chips are safer than mag stripes if you can just swipe your card anyways | [
"This is either a fault of the system in your home country, accepting swipes for chip cards when they shouldn't, or is a deliberate use of both during a transition period - the stripe only exists as a backup during the time your country is moving to chip & pin. After a certain date, the mag stripe should no longer ... | [

Why are we still driving on inflated rubber tires? | [
"Today's tires have very little in common with the tires of 50 years ago beyond being rubber & filled with air. The way their built & the materials they use have been continuously refined & improved."
] | [
"The first tyres were solid. They didn't work well, making the ride bumpy as hell. There air in inflatable tyres gives a less bumpy ride, and improves grip and handing. Despite having to deal with punctures, the advanntages of inflatable tyres far outweigh those of solid ones."
