The Elements video

I liked the elements video because it was very informative while entertaining at the same time.  What I didn't like is that sometimes they would have text at the bottom telling you facts but sometimes you wouldn't see them and you would miss out on the cool facts.  My three favorite elements are oxygen, helium, and potassium.  I like oxygen because it keeps us alive.  I like helium because it makes balloons and it makes your voice high if you breathe it in.  I like potassium because potassium is good for you and it is in bananas.  My least favorite elements are Plutonium, Uranium, and Hydrogen because they are all very dangerous.
