When people think chemistry, they think BOOM!!! cool explosions, loud noises. Ever wonder why is that?
Here's a great perspective from a chemist's view on the excessive use of explosions to 'sell' chemistry. Yes, science does sometimes have explosions, but for the most part, science exploration is not earth shaking in that sense.
Working with children in the past few years, I have learned that there are many really cool and exciting experiments one can do with children, which are safe, yet entertaining, and yes, you can still learn a lot from them.
