Over the weekend Isabel went to the Fiesta. She got some fantastic photographs for our Prezi, and did some interviewing. David and I did some testing with the construction we had @home. We ended up setting it on fire twice; the second time to the point of ashes. We did get some footage, which I hope will be posted soon.
Today in class we did further testing on the cylinder balloon. We had attached 10 candles to the balloon, and started getting some lift. A slight breeze caught the side on fire, and we were able to put out the flames before irreparable damage was done (thanks to Alum!). The hole was patched.
We also worked on assembling the equilateral balloon, cutting out some tissue paper models and applying Alum to the tissue. We discussed some balloon construction factors with the other balloon lab group such as: potential energy of fuel sources; cubic foot space of the envelope ratio for lifting the weight of the entire construction; internal temperature of the envelope vs atmospheric temperature.
