Limes float, but lemons sink. Because limes are denser than lemons, they sink to the bottom of a glass, whereas lemons float on top. This is the one that has been in front of our faces (or rather, in our glasses) the entire time! Check out these other things to ponder that you probably never considered before.

It's probably pretty simple for you to picture what you think of as an igloo, yet this is not the true definition of the word. The word "igloo" refers to any sort of dwelling, even though some Inuit currently do or have lived in the dome-shaped structures made almost entirely of snow and ice. Consequently, your home, whether it be a chateau in Europe or a studio apartment, is an igloo.

For a period, astronomers referred to 55 Cancri e as a "super-Earth." A super-Earth is a planet that is far larger than our own—in this example, twice the size. 55 Cancri e is so near to its star that it orbits it in just 18 days, despite being 40 million light-years away in the Cancer constellation. One of its most astounding attributes, because to its proximity to its star, is its temperature, which registers a stunning 4,900 degrees Fahrenheit (2,700 degrees Celcius). That heat, along with the density of 55 Cancri e, led scientists to hypothesise that the planet's core was composed of carbon in the form of diamonds and graphite.

The basic idea behind cruising across the shores of a river is to derive utmost pleasure, and there is no better way to cruise off the Brahmaputra coast than to board the M.V Mahabaahu.

Thor's most renowned weapon is his hammer, Mjolnir, which was constructed in an astronomical manner, very literally. In the Marvel world, Thor's hammer was forged in the centre of a dying star. When a star dies in our universe, its core burns so hot that it creates a dense substance known as "neutronium." A single teaspoon of the substance, like Thor's hammer, is thought to weigh billions of tonnes. Some of the science in Marvel's Thor films is based on beliefs we know in this reality to make it more credible.

Many of us are aware that Papua New Guinea is densely forested, but did you realise it also possesses the world's third largest rainforest? Papua New Guinea contains a 288,000 square kilometre rainforest, ranking third after the Amazon and Congo Rainforests.

Here's a great advantage you can point out to make the "breast is best" zealots jealous: researchers at the Medical Research Council Epidemiology Unit in Cambridge discovered that formula-fed babies cried less, smiled and laughed more, and were easier to calm than breastfeeding babies. The ostensible reason? Breastfeeding is difficult for newborns, and some may not feel up to the endeavour and will fuss. Formula feeders have an easier difficulty filling their stomachs, so it's no surprise they're happier!

It assists the user in being emotionally alert without losing a component of "being human."

If the Bible contains the earliest reference to the passport, the origin of the two French words 'passer' + 'port' meaning "to pass through a port" dates from the 15th century. It was also written as a compound word at the time, "passport." From the middle of the 15th century, the compound name "passport" was used to refer to the movement of people after it was first used to authorize the movement of goods. However, it is not certain that the term "port" referred solely to seaports, but rather to the gates of fortified cities.

There is a whole business dedicated to creating the flavors of grocery store foods. Working with phantom aromas or aroma-taste interactions, scientists discovered that consumers link "ham" with salt. Simply adding a ham-like fragrance or flavour to a cuisine might cause your brain to interpret it as saltier than it is. The same idea applies to the aroma of vanilla, which many associate with sweetness.

(Once again, contact your doctor before adding to or modifying your medical treatment plan in any way.)

The orientation leaflets are arranged in one or two pinnae pairs in a bipinnate compound. Each pinna also contains 10 to 26 leaflets. These plants grow on soil with little nutrient concentration and are not shade-tolerant.
