|Happy Earth Day!|

Every year around Earth Day, my daughter and I try to come up with ways to help protect the environment, with a big focus on the Three R's, Reduce, Reuse and Recycle! We've held Earth Day Parades, toured recycling facilities, and have built a model town for Katie's toys out of recycled materials! This year, we wanted to spend Earth Day thinking about our atmosphere, and exploring some of the more interactive properties of it. Namely.... air pressure!
Every day, we sort our trash into recycling. We go through a lot of aluminum cans in our house, as we all enjoy sparkling water. I crush these cans every day, and one day I got to thinking, what if I could crush these cans, not with my hands, but with AIR? Thus, our Earth Day experiments were born!
