My boys received a package of rocket balloons as a gift from a dear friend. These balloons launch fast and fly high. My boys love them.

We spent a beautiful afternoon outside learning about aerodynamics, the force of propulsion, using power to push an object forward, creating and controlling thrust, and what happens when air moves from a high pressure to a low pressure environment, all in a fun, hands-on manner. We discussed fueled rocket launches and hovercraft. We even discussed animals, such as squid, jellyfish and octopi, which use propulsion in order to move.

The only downside to this afternoon of fun? We now have lots of balloons caught in trees and bushes around our yard that we have to figure out how to recover and remove.
