So I decided to make an educational blog about stuff that I found interesting.

1. Only 3 countries are not in the United Nations: Vatican City, Kosovo, and Taiwan.

2. The Wright Brothers' first plane flight could have taken place in the cargo hold of the Antonov An-225 (World's biggest plane).

3. Dry ice (Frozen carbon dioxide) is made by pressurizing a room filled with caarbon dioxide and refrigerating it until it becomes solid. Also, it is cold enough to burn you, or give you frostbite. Don't touch it with bare hands or eat it.

4. Mentos and soda make explosions because pores in the Mentos react to the carbon dioxide in the soda, causing a release of all the foam in the soda.

5. That new car smell is made of the smell of over 50 volatile compounds.

6. Pluto takes 248 years to orbit the sun. That means that it didn't even complete one rotation before it was classified as a planet then unclassified again.

7. Gasoline, propane, and other fuels don't smell on their own. They add a chemical that you can smell if there is a leak, which can obviously cause something to blow up.

8. The last time people visited the moon was in 1972, and all the lunar rovers and some American and Russian landing craft are still there. They probably costed more than 200,000 dollars each back when they were new.

9. In the 1950s and 60s, computers were the size of a large room, and could still only do basic things.

10. Most fire trucks are red because in the 1800s, fire brigades competed to see who had the best looking pump. Since red was the most expensive color, they usually painted their pumps red. Also, it helps people see it easily since most cars today are white or silver.
