1. The black dots on your french fries.
We’ve all encountered those black dots on our French fries at least once in our lives. They might look really gross, but, in fact, there is nothing harmful about them. They are just pockets of sugar caused by the cold when keeping them in the refrigerator. When your fries are being cooked, thanks to the heat, these sugar pockets turn black because the outside of our snack cooks faster than the inside, and they burn.
2. Coal in peanut butter.
We have seen many times that coal in peanut butter can be turned into diamonds. It’s actually possible to turn a piece of coal into a bright expensive diamond, but it’s not as easy to do, despite how simple people on the Internet make it seem. In order to actually turn the goal into a precious stone, you need special equipment that can generate a huge amount of pressure. But even with this, the process takes weeks to produce just a small diamond of 3 millimeters in diameter.
3. The mystery of rainbow corn.
This rainbow corn is actually called glass gem corn. This type of corn has such an unbelievable combination of colors that it’s quite hard to believe unless you see it with your own eyes.

7. The Eiffel Tower can grow up to 15 centimeters.
In the high temperatures of summer, thanks to thermal expansion, the iron heats up and starts to expand. That’s why the Eiffel Tower can grow up to 15 centimeters.

Human teeth are the only part of the body that cannot heal themselves, as they are coated in enamel, which is not a living tissue.
9. Snowfall in the Sahara Desert is an unusual phenomenon.
Seeing snow on the sand dunes of the Sahara Desert is quite a rare phenomenon to encounter, however, it happens. In order for snow to appear anywhere, we need 2 properties: cold temperatures and moist air. Even though the Sahara is mainly known for its very high temperatures, there are also very very low temperatures, as low as 7°F (-14°C).
Thanks to the bare land surface and cloudless skies at night, snow easily forms during winter air circulation, and moist air is drawn toward the northern Sahara from the Atlantic and Mediterranean oceans.

Back in the day, door keys used to be much bigger than the ones we use now. Because different types of architecture used different-sized doors, a bigger door required much bigger keys.
