Alligators are some of the most vocal reptiles! ๐
Alligators have a variety of different calls to declare territory, signal distress, threaten competitors, and find mates. Although they have no vocal cords, alligators bellow loudly by sucking air into their lungs and blowing it out in intermittent roars. In addition to bellowing, alligators can growl, hiss, and make a cough-like sound called a chumpf.

โซ๏ธ Where in the world do the rich work more than the poor, and where do they work less?
The biggest difference in average hours worked by rich and poor is in Belgium: the 10 percent of people in that country with the highest incomes work on average 7.7 hours more per week (!) than the 10 percent of people with the lowest incomes. Overall, in many Western countries the rich work more than the poor: in Germany the difference is 5.4 hours, in New Zealand, Iceland and Great Britain it is more than 2 hours
On the other side of the ranking are mostly Asian countries: in India, the rich work 7.3 hours less(!) per week than the poor; in South Korea, 7.1 hours; in South Africa, 7 hours
There is no difference in working hours between rich and poor in Norway and Hungary, the minimum difference is observed in us (the rich work on average 0.1 hours less than the poor)

Dry water
Everyone knows that the water is wet. But what if I say that there is dry water? This liquid is very similar to ordinary water, but has opposite characteristics.
For example, it weakly moistens and evaporates very quickly. And it also boils at 49 degrees, so you can immerse your fingers in boiling dry water and not be afraid of getting burned. But it will not be possible to brew warm tea, since dry water rejects other substances, for example, dyes.
The vapors of this substance are so heavy that they can even extinguish candles. Dry water also does not conduct electricity, so a phone that has fallen into such water is not in danger.

Why doesn't ice sink?
Nowadays, 5 amorphous varieties and 17 crystalline modifications are known for ice โ water in solid aggregate state.
However, in the natural conditions of our planet, water crystals only have one modification โ the so-called hexagonal syngony.
Due to this structure, the density of ice is less than that of liquid water, so it doesn't sink.
