Beach weather gives us the opportunity to get outdoors, enjoy the fresh air, and soak up some Vitamin D, but also brings concerns about excessive sun exposure. With stronger and more frequent sun comes a higher risk for skin to be damaged by UV rays, making the body more susceptible to skin cancer.
Skin cancer is one of the most common types of cancer. The Skin Cancer Foundation states that more people are diagnosed with skin cancer each year in the U.S. than all other cancers combined. The cause is most often UV rays from the sun or tanning beds. Skin cancer is generally categorized into two groups, melanoma, and nonmelanoma.
Melanoma cancer begins in melanocytes, which are cells that produce skin pigment (melanin) and reside deep within the epidermis (the outer layer of the skin). Melanoma is known to often be more serious than nonmelanoma cancer because it has the tendency to advance and spread rapidly. The number of new melanoma cases are also on the rise. That being said, the ea…
One of the more fun classes in high school was chemistry lab, especially on the days when you made things explode or catch fire...on purpose.
Relive those good old days with our videos of exploding chemistry experiments.Stock Videos of Exploding Chemical Reactions
The Barking Dog experiment and the Rainbow Clock were very popular. But it's hard to beat the surprisingly loud explosion of a nitrogen triiodide explosion when it's touched lightly by a feather.
And no one expects a tiny piece of metal dropped into water to steam, hiss, dance about and eventually explode, but lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and caesium (Cs) do exactly that. Gifts for the Chemistry Geeks
Here's what happens in each reaction:
Let's check what happens if we would drop a pea-size piece of metal in water.Lithium just sizzles on top of the water, but doesn't explode.Sodium floats on top of the water, then ignites with a yellow-orange flame and also doesn't explode…
