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.

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.

Flame

• Flames are made of Plasma, gases that are heated to the point they have lost some of their electrons. 


• Flames are magnetic, most flames are repelled by magnetic fields. 


•On the international Space station there is no gravity so candle flames won't take a teardrop shape, instead they burn as a sphere shape with blue tinge.
