Don't try this at Home!
If you drop a frog into boiling water it will hop straight back out again, but if you put it in cold water and heat it slowly the frog will boil to death.

Recycling works
There is the exact amount of water on Earth today as when the Earth was formed. Water is never totally consumed. It always recycles itself, in one form or another.

Word play
It is possible to drown and not die. Technically the term 'drowning' refers to the process of taking water into the lungs, not to death caused by that process.

Marketing trick
Juice that has 'all natural' written on the label even if it has less than 20% or 10% of juice... the water is natural, so the contents are 'all natural'

Sense of smell
The elephant can smell water up to 3 miles away. Also, a dogs' nose is so sensitive that it can tell the difference between a tub of water and a tub of water with a teaspoon of salt in it.

Eavesdroppers
Why are those gossip-hunting spies called eavesdroppers? It is because in Middle English, the water that falls from the eaves of a house was called eavesdrop, and eavesdropper was first used to describe someone who would stand close to a house in order to hear what was going on inside.

Holy water
The Catholic Herald, published in Great Britain, warms about the dangers of drinking holy water from religious shrines. While it may have curative powers in a religious sense, it seems that it also is a breeding ground for germs.

Old Faithful
Old Faithful, a geyser in Yellowstone National Park, can spout water 170 feet in the air. That is as high as a 17-story building

Fancy a Big Mac?
In Australia, a scientist put a Big Mac in a desk drawer and left it in there for a year to test the preservatives. When he pulled it out a year later, there was not a speck of mould on it. The only only thing different was that the buns were hard. He then microwaved it with a cup of water and ate it.

De-caf water?
There are almost 800 different brands of bottled water for sale in the United States.

On the move
The great pyramids of Egypt now stand a full 3 miles south of the spot where they were originally built. That's how much the earth's surface has shifted in the last 4500 years.

Spooky
The three pyramids of Giza do in fact match the belt of Orion, but they did not when the pyramids were built. It seems that the Egyptians built the pyramids to resemble today's belt of Orion.

Keeping busy
All of the signifigant major pyramids were built over a time period of about 200 years. A new one was well underway before the previous one was completed. It amounted to keeping a more or less constant work force busy the year around for the 200 years.

Sand & Cement
The Egyptian Pyramids were not made from cut stone. The blocks were poured in place using crushed, local limestone and a 'geopolymer' - a cement that is better than most known today. The largest was built in 20 years using an estimated 14,000 workers.

So there!
The biggest Pyramid in the world is not in Egypt. It's actually about sixty miles southeast of Mexico City, Mexico. It covers more than forty acres and the largest Egyptian Pyramid, The Great Pyramid at Giza, covers about 13 acres.

Tallest
The Great Pyramid at Giza in Egypt, constructed around 2500 B.C., was the tallest building in the world until the Eiffel Tower was erected in 1889.

A big job
More than 14 million sandstone blocks make up the pyramids which were originally covered in limestone. Funnily enough this limestone wasn't stolen but used by the native egyptians as building material.

No wonder that tower's leaning!
Pisa, Italy is six miles from the coast of the Mediterranean now, but that sea rises and falls over the ages and Pisa was a port city in the 5th century B.C. A couple of years ago excavators found 15 ships with antique cargoes intact buried in the clay under Pisa where it was left by withdrawing waters.

Busy town
The most populated city in the world is Shangai in China.

Obvious really!
In Caracas, the capital city of Venezuela, it is customary for the streets to be blocked off on Christmas eve so that the people can rollerskate to church.

Run for the hills
Using satellite-surveying techniques, scientists have determined that Los Angeles, California is moving east. At a rate estimated to be about one-fifth on an inch per year, the city is moving closer to the San Gabriel Mountains.

Tiny cities
The Vatican city, as well as being the smallest city in the world, is also one of the only countries within another country (it is inside Italy) The other is San Marino, also inside Italy

Tax and Architecture
A building in Belgium was taxed if there was a street light on it...unless a statue of the Virgin Mary were place above it. Hence, there are no buildings in the city without a statue of the Virgin Mary.

I'm going to need a bigger envelope...
The longest official city name in the world is: Krungthep Mahanakhon Amorn Rattanakosin Mahintara Yudthaya Mahadilok Pohp Noparat Rajathanee Bureerom Udomrajniwes Mahasatarn Amorn Pimarn Avaltarnsatit Sakatattiya Visanukram Prasit. It is the official name of Bangkok, Thailand.

Local Laws
In Chester, England, you can only legally shoot a Welsh person with a bow and arrow inside the city walls and after midnight. The only trouble is finding one ;o)

Growing fast
The first city in modern history to reach 1 million people was London in 1811

Geography
We usually think of Montreal, Canada as a cold weather city, and Paris, France as a much warmer city than Montreal, but the fact is that Montreal is south of Paris.
