Up, up and away! Analyze why hot air balloons fly and how temperature affects air density. You will be able to construct and fly hot air balloons made out of tissue paper and use hot air for their fuel. We used a great template from Pitsco. Click here to buy the supplies to make your own. You can follow along with the step by step pictures. Don’t forget to share your finished hot air balloons on Facebook and Google+.
