Why do mirrors' reflections turn green when they're faced against one another?	[ "The glass itself must be slightly green. A single reflection through one layer of the glass won't have a noticeable color change, but bounce the image through more and more layers and it will." ]
How we find oil and then get it?	[ "Modern scientist use sensitive gravity meters to measure tiny changes in the Earth's gravitational field that could indicate flowing oil, as well as sensitive magnetometers to measure tiny changes in the Earth's magnetic field caused by flowing oil. They can detect the smell of hydrocarbons using sensitive electro...
Why melting ice DOESN'T overflow a cup?	[ "When ice is floating, it displaces its weight in water - so dropping some ice onto a glass of water causes the water level to raise proportional to the weight of the ice. When that ice melts, it turns into water, which technically still only displaces its weight in water, so the water level won't change.\n\nSea le...
Why can humans initially recall the details of a dream upon waking up, only to forget even the most basic details of that dream shortly after?	[ "Here's some links to posts where other people have asked this question. I'm only posting a few, but you can find more instances of this question being answered if you search the sub-reddit for \"remember dream\".\n\n_URL_4_\n\n_URL_1_\n\n_URL_3_\n\n_URL_2_\n\n_URL_0_" ]
why does our vision have green blobs after looking at the sun or bright light for extended periods of time?	[ "Promise me you will never look at the sun without eye protection! Basically what happens is that our eyes focus the image on the back of the eyeball where there are millions of sensors called cones (they see colors) and rods (they see black and white). Each of them has pigment (like liquid ink) in them. When you l...
what causes the sound that we hear when a car passes by? And why does driving past stationary cars also make the same "whoosh" sound?	[ "The sound that gets higher as the car approaches and then gets lower as it drives away is caused by something called the Doppler effect. As the car is driving it always products some sounds, as it goes towards an observer the sound waves it produces get scrunched together slightly, causes the pitch to go up. As th...
Why don't they fill my drinks up all the way at drive-throughs?	[ "Speed. It takes minute sometimes for the suds to subside in your Coke. A minute that people sit and fuss about and corporate takes notice", "At the fast food place I work, there is a limit to high how we are supposed to fill. It is marked as a little horizontal line near the top.\n\nA reason why some places may...
Why a group of people sounds loud even if every single person is speaking at a normal volume?	[ "Because it is louder. At least some of the sounds create \"constructive interference\" resulting in the actual sound wave to your ear being louder than each individual voice.", "Sound waves can join forces with each other to get louder, so if you have a bunch of sound wave sources in one area it will sound loude...
