>Q: Why are raindrops shaped like tears?

A: The water molecules are polar, so they want to turn to the polar magnetic field of the Earth. But when the molecules begin moving toward the magnetic field, the Coriolis force makes them turn upward In the southern hemisphere, raindrops look like upside-down tears.

>Q: Why does glass flow down old windows but not new ones?

A: Anything made out of glass is disturbed by waves at its resonant frequency. In old windows, the resonant frequency was often the same as the frequency of sunlight. New windows are designed not to have this problem.

>Q: Why are eggs easier to balance on the day of the equinox?

A: At the summer equinox, the Earth is at its closest point to the Sun. This means that the Sun and the Earth pull on the egg in precisely opposite directions. The forces from the Earth and Sun cancel each other out, so the egg has zero angular momentum.

>Q: Why is our galaxy expanding?

A: The stars in our galaxy are close enough together that once in a while, one star passes in front of another and blocks its gravity. Every time this happens, the galaxy expands a little.

>Q: Why does tapping the side of a pop can keep it from frothing over when opened?

A: Pop cans explode because the carbon wants to get out of the can. When you tap the can, some of the carbon hits the side of the can and combines chemically with the aluminium.

False. When days of equinox occur the atmosphere expands further into space and every schoolchild knows about density and gravity

>"The artistic representation of raindrop as presented by popular culture is that of a teardrop. Actually, real raindrops bear scant resemblance to this popular fantasy (except after they have ceased to be raindrops by splattering on a window, say)."


>"Small raindrops (radius < 1 millimeter (mm)) are spherical; larger ones assume a shape more like that of a hamburger bun. When they get larger than a radius of about 4.5 mm they rapidly become distorted into a shape rather like a parachute with a tube of water around the base --- and then they break up into smaller drops."

>"This remarkable evolution results from a tug-of-war between two forces: the surface tension of the water and the pressure of the air pushing up against the bottom of the drop as it falls. When the drop is small, surface tension wins and pulls the drop into a spherical shape. With increasing size, the fall velocity increases and the pressure on the bottom increases causing the raindrop to flatten and even develop a depression. Finally, when the radius exceeds about 4 mm or so, the depression grows almost explosively to form a bag with an annular ring of water and then it breaks up into smaller drops."

quite a nice list of creative but very incorrect (troll) answers...

1. they're spherical

2. old windows were never flat. they were always thicker on one side bacause of the way they were made. occasionally you can find an "upside down" window that is thicker on top

3. this is just plain stupid

4. no. not even close.

5. when you tap the side of a can you release the carbon bubbles that have attached to the side. the bubbles float to the top of the can. when you open a can with bubbles on the sides they try to escape and pull liquid with them, if they are already at the top the fluid is undisturbed

>> No.1131852

Q: Why do the continents move?

A: There is oil below ground. A lot of it. This lubricates the plates the continents ride on. The eventual removal of all the oil in the ground will then freeze the continents in their place. There has been evidence that the continents are indeed slowing and this is the cause.

>Q: Why are raindrops shaped like tears?

A: God is crying because you touch yourself at night.

>Q: Why does glass flow down old windows but not new ones?

A: Because, in the olden days, people went to church and respected god. But nowadays, people don't. Glass flowing down a window is a sign of god's blessings.

>Q: Why are eggs easier to balance on the day of the equinox?

A: Think back to Easter. Remember that the equinox represents harmony because the planets are lined up, just like how Easter is harmonious because Jesus died for your sins. Why else would we decorate eggs on Easter? Because they balance on the equinox.

>Q: Why is our galaxy expanding?

A: It's not. The scientists are trying to use an "expanding" universe as evidence for a "big bang" that's calculated at 13 billion years ago, but this can't be true because the bible says the Earth is only 6000 years old.

>Q: Why does tapping the side of a pop can keep it from frothing when opened?

A: Pop cans explode because you haven't recently confessed your sins, and God is trying to remind you. By tapping the can, you're telling God that you'll remember to confess.

why d you turn red when you're hot?

because you'tr body is warm enough to emit light in the visible light spectrum, which starts at red.
