Science Experiments For Kids

In high-school science was always one of my favorite subjects. I was one of those students always pestering the teacher with questions about why stuff happens. As I was cleaning out some of my stuff last week, I found a collection of my science experiments for kids. As they don't really help me anymore, I have decided to post a couple here.
So here are some of my science experiments for kids
