Bin Bag Aircraft. A $50 science experiment
“The project consisted of three major components: trash bags, payload, and a parachute. The payload consisted of a GPS tracking device and a digital camera to take images of the journey. After planning the project thoroughly, I chose August 24th because that day was very warm and clear with light winds. T.B.A.C managed to stay in flight for approximately 3 hours and captured roughly 2000 pictures using a 3 second interval.”
Here’s a time lapse of the pictures captured by the Cannon A495 Digital Camera attached to the balloon / bin liners.
