Human ova do not have hard shells like chicken eggs.

Sugar is significantly heaver than water though which would only increase the density of the cola.

Reply to eli5 How does measuring area in square miles work? If you have very mountainous terrain, does that increase the area compared to somewhere that is very flat? by bluejeans90210
If you're measuring surface area yes.
If you were to look at God's eye view of a 1x1 mile square of land. One flat, one mountainous, the flat would appear bigger.

A liter (L) is a unit of volume, while a kilogram (kg) is a unit of mass. The two units are not directly related to each other, as they measure different quantities.
To convert between liters and kilograms, you need to know the density of the substance you are measuring. Density is the mass of a substance per unit of volume. For example, if you have a liter of water, which has a density of 1 kilogram per liter, the mass of the water is 1 kilogram.

Blame the UK, cups-pints-quarts-gallons make sense over here.

How are you making you coffee very hot? What is the heat source, and where is the coffee when you add the brown sugar?

If I even think about anything tart, like a sour candy, that gland starts pumping out saliva to a painful degree. It’s like a yawn with a mouth full of glass. Oops there it goes.

Reply to eli5 why is the winter solstice not on the same day as when the earth is closest to the sun? by o_pyrite
The solstices are tied to the tilt of the Earth's axis. They are the points when the axis is either tilted the most towards or away from the sun. This change of the orientation of the Earth's axis has a larger effect on the seasons and climate than the change in distance of the Earth to the Sun.

Reply to comment by SirDuke6 in ELI5: Why does putting one foot out from under the blankets bring so much relief of heat while laying in bed? by SirDuke6
It's a psychological effect. Just like the drinking water provides "immediate" relief even though it really doesn't. It's your brain rewarding itself for doing something it decided it needed to do to survive. The brain is funny like that.

The solstice is a result of a planet's axial tilt (i.e. the planet does not spin perfectly straight "up"), and the perihilion (when the earth is closest to the sun) is not related to axial tilt but instead to where in the not-perfectly-circular orbit we are.

The solstices are a function of Earth’s axial tilt, occurring when you’re pointed at the minimum and maximum angle.
This is independent of the Earth’s orbital characteristics, although the northern winter solstice does coincidentally occur near the Earth’s “perihelion” - the closest approach.

I want to expand on this. 1.5L of water weighs 1.5kg by definition. The original definition of the mL was the cubic volume of 1g of pure water at 20°C. So it's is not a coincidence that these numbers are the same, or that the density of pure water is 1.0000, it is so BY DEFINITION.

Yes. If you're ever really hot, run cold water on the inside of your wrists. Those veins are near the surface and lead directly to your heart. It'll cool you down so fast it's crazy.

Solstice has nothing to do with the orbit of the sun or proximity to the sun.
It is about the angle of the earth relative to the sun. The earth leans a bit. For half the year, the southern hemisphere faces the sun more directly, the other half the northern hemisphere faces it more directly.
Summer/winter Solstice marks when the lean is most head on/most leaning away to the sun for each hemisphere.
This happens on the same day each year because the lean is constant.

True, however can be calculated from volume by using the density of the substance.
