Balloon propelled lego car. LEGO Education Simple Machines and a LEGO Balloon Car Homegrown Learners One of the best additions to our LEGO resources has been the Simple Machines set from Lego Education. Not only has my son enjoyed free building with this set but he has also sat down with the many instructions and has begun to build and experiment on his own. Learn how to build a car from Legos that is propelled by a balloon.

When the air stored in the balloon rushes out through the narrow opening in the straw it exerts a force on the car action. The idea is simple. Stick the balloon through the hole with the lip of the balloon facing the back of the boat.

Air is forced out of the end of the balloon which means there must be an equal and opposite reaction pushing the car forward. We were inspired by Davis Creek Elementarys post about Lego cars. Make cute little monsters using foam pom poms and pipe cleaners.

This is your cars propulsion system. To propel the car blow up the balloon then twist it a little to keep the air from escaping. Make a small hole on the boat with the LEGO bricks to hold the balloon in place.
