Hot Air Balloon V. 2.0

The Design!

Design

The design and materials used for our second hot air balloon didn't differ much from our first. We chose to use the same garbage bag as we did in the previous hot air balloon, deciding that a normal grocery bag would be too small. However, rather than using straws, we used wire to connect our candles to the garbage bag. We also chose to use 10 small birthday candles, attaching them to the wires by using tape and small pieces of straw. We had hope that by using a few more candles than we did in the previous experiment, we would be able to produce enough heat to fill up the large bag, allowing it to float.

Results

Unfortunately our bag was still too large to be able to float. As for improvements, we could use a smaller garbage bag and perhaps a different design that would hold the candles in place better.
