An animated explanation of hot air balloons.
Director's Notes:
Team FALB describe their film:
It starts with a demonstration of air expanding in a plastic bottle when heated. This is followed by a hand drawn demonstration of what goes on in a balloon when the air is heated (loss of mass as the air expands and molecules leave the envelope). There is a brief explanation of lift vs. gravity in terms of weight loss. Final frame of a Chinese Sky Candle lifting off.
The team was one nine year-old, and his dad.
Winner: Ignition* Best Film from the East Midlands, 2010
SciCast Notes:
Most SciCast films come from school groups. Increasingly, we’re seeing groups of friends making films on their own time — often the year after they’ve made films in school — but this is the first year when we’ve had many films from families.
You know what? Something like this is a lovely weekend family project. We always thought this — see Stanley’s Balloon Flute, one of the very first SciCast test films, made with my nephew — but it’s difficult to get word out to families. I’m delighted people are starting to pick up on the project.
Besides all that, this is a delightfully charming film. Lovely.
