Water and stuff

When you cool water down it shrinks until it gets to about 4° C, then it starts to expand, when it solidifies as ice at below 0°c it has expanded so much that it floats on liquid water. 

Water would boil at room temperature in a vacuum, it is the air pressure that decides the boiling point of water. 

You can break water molecules with two wires and a 9 volt battery. When a certain amount electricity passes through water, it causes the oxygen and hydrogen bonds to break, this would cause oxygen and hydrogen gas to bubble at the surface. 

The alkaline metals Lithium, Potassium and Sodium float on water, they also react with the water causing a release of hydrogen gas. 

The Butterfly effect

The butterfly effect is a concept of chaos that points out that a small effect can trigger a chain reaction that can lead to a much bigger effect. The main example of the concept is that it could be possible for a butterfly to flap it's wings, the air flow away from his wing tips could cause a chain reaction that goes around then planet and eventually turns into a hurricane. 

I can think of unlimited examples myself. I could ask a person what time it is? My face reminds them of their boss at work, this causes them to call their boss to ask for overtime, the voicemail on their manager's phone is music. The music reminds them of a hang gliding. They decide to try the hobby again on the weekend but accidentally hit some power lines, they're fine but the power supply for the town is cut off for one day. The loss of power causes a pilot to miss his flight. The pilot was due to make a grave mistake that day and crash a plane but the flight never occurred. In this scenario, by asking for the time I cut of the power to the whole town and also save the lives of 550 people. If I didn't ask a stranger for the time, the power wouldn't be cut off and a airplane is crashed because of pilot error. All those events hinge on a small thing. That is just one example. 

Grandfather Paradox

If you travelled back in time and caused yourself to never be born then you would not be able to go back in time and cause the event because you were never born. This paradox is known as the grandfather paradox. 

A common example of the grandfather paradox is if you got in a time machine and visited your grandfather before he had your father. If you shot him then your father wouldn't be born and neither would you, but then there is no one to shoot him because his assassin was never born. 

That is the grandfather paradox. 

One Thousand Ancestors

If you looked back 200 years at your family history, you would likely find 1000 of your ancestors existed. This is because each person in the family tree came from two parents so every generation you look back doubles in size. 

You have 2 parents, 4 grandparents, 8 great grandparents, 16 great great grandparents. 

Just 100 years back and there are 30 ancestors. 

You have 32 great great great grandparents, 64 great great great great grandparents, 128 great great great great great grandparents, 256 great great great great great great grandparents and 512 great great great great great great great grandparents. 

That is 1022 ancestors, roughly one thousand of them existed at some point during the last 200 years. You would need two large passenger planes to contain them all. 

It is hard to know exactly how many ancestors you have because some of them may have been distant cousins and some of them have children at different stages of their life. But I estimate it to be roughly 1000 individuals over 200 years. 

American Flag

The American flag has 13 stripes, they represent the original 13 British Colonies on the east coast of America. 

There are 50 stars on the American flag, they represent the present number of member states of the union. 

Hidden Game

On the Google Chrome Browser, you may see an image of a dinosaur if your smartphone is on airplane mode or you can't get an internet connection. 

If you press on the Dinosaur, it turns into a black and white side scrolling computer game. 

Eggs

• Chickens eggs are made of a giant single cell, that is "eggCellent'. 

• Chickens can ley an egg once a day. 

• Chickens eggs are actually periods because they are not fertilized. 

• Ducks eggs are the same size as chickens, the shells are completely white. 

• Chickens eggs are often used to make vaccines because viruses hijack the egg like a cell and can fill the whole egg with virus particles that can then be used to make the vaccine.
