Balloon Powered Race Cars: Race Day

Today, we began to race our cars.  I saw some really good models and others that could use some more time and effort.  Thus, I will allow for over the weekend for kids to reconstruct their vehicles and race again on Monday.  Those that raced today were given extra credit for preparedness.  So, check out the rules (see Monday's post) and build the best car you can!  Prizes for greatest distance covered, fastest car and coolest car.  Check out Google Images:  Balloon Powered Race Cars as well as YouTube for some great ideas.
