The Dawning of a New Era

With the Coyote Physics out of the way and long behind us, a new project rises on the horizon.  Almost literally.
Katie, Nikki, and I have started working on a hot air balloon.  The design we're using comes from M.W. Worman's design plans.  We halved the measurements to a more manageable size.  Last week we cut and pasted the parts of the tissue paper that we needed together.  This week we hope to have it in the air.
We'd like to learn the physical reasons why the hot air balloon rises.  We know it's to do with heat rising, but can we measure that?  Can we calculate the buoyancy of the hot air balloon?  And what can this teach us about thermophysics?  When this project is done, I'll use the information we gain from it to add to the physics wiki.

And once we've perfected the art of hot air balloon making, we'll use them to take over the world!!!
