Let's have a balloon race to put our new understanding of hot air into action!

We need to use a lot of our own energy to put air into the balloon. 

We tied our balloons to a string and let them go!


We know that our bodies use energy the same as the balloon: the more we exert, the more energy is expelled!

Who will win? Watch the video below to find out!
