The “Scoville Scale” measures the hotness of peppers.
The surface of the sun
is roughly 10,000°F.
At the core, temperatures
can reach over
25,000,000°F.

Hottest recorded temperature on Earth:
136 °F – El Azizia, Libya

Created by friction, the ignition temperature for a match is around 360°F.
Once burning, the initial burst of heat can reach 1100°F.
Color Chemical Compound
Red strontium, lithium
Orange calcium chloride and sulfate
Gold incandescence of iron, charcoal
White magnesium, aluminum
Green barium and chlorine
Blue copper and chlorine
Purple strontium and copper
Silver aluminum, titanium, magnesium
How do they make different colored fireworks?
By using different powdered elements in the shell. Here are just a few of the elements and the colors they produce.

Peppers have a chemical called capsaicin - this is what makes them hot.
Because of the effect it has, capsaicin can be used to treat arthritis, headaches, and neuropathy.
Peppers can also be used as a deterrent against insects, squirrels, and elephants.
Of course, there is always pepper spray to fend of an attacker or a bear.
Every 4th of July, there are an average of 14,000 public fireworks displays.
The Inner Core of the earth, made up mostly of iron-nickel alloy and more than 2,000 miles under our feet, is estimated to be just as hot as the surface of the sun – 10,000°F.
Lava, or molten rock, flows from beneath the Earth’s surface and reaches temperatures between 1300 and 2200°F
