Simple Science Frozen 2-Liter Bottle Experiment

I found this on Homeschool Creations' website.
What will happen to a quarter put on top of a soda bottle that has just come out of the freezer?

Items we used for this experiment:

~ 2 liter bottle

~ quarter

~ a little cold water

You may be surprised. See her site to see what her kids found out!

Celestial Rock Stars

Meteors fall through our atmosphere in the form of "Celestial Rock Stars", so tells us a great site called: "Wonderopolis"!
There is a meteor shower this week, by the way!
