This week in science class we started a new project to design and create a functioning model of a hot air balloon. The twist is that all the supplies cost a certain amount of money and we are on a budget. For example plastic bag costs $500 and a paper cup cost $300. Also instead or having the air to be heated in a burner, or even with a candle the hot air will be coming from below. This is to prevent obvious fire hazards.

I am in a group with with Mosie and Harrison. We are trying to create a light design. One that opens the bottom of the envelope more then a traditional hot air balloon to catch more of the air. We want it not only to float to using hat air but also somewhat like a sail. The bottom will have two dowels in a X shape connected to the balloon with hot glue. our last step is to ad a tiny aluminum foil basket at the dowels because it requires a basket. We were going to attach it with wire. Instead we chose hot glue because it was cheaper and more secure.

Questions:

How much is the budget?

Have you tried this project before?

Have the hot air balloons actually floated before?
