Hot Air Balloon 2
Materials
- a bag
- 5 candles
-straws

Our group began with an idea similar to our final product. The same shape but we cut the straws in half lenthwise to reduce the weight of the duct tape we used. Our candles were also cut small to reduce the weight of our hot air balloon. We used duct tape instead of the masking tape in the end because the masking tape was not string enough to hold the bag and straws.
When we were done making our hot air balloon, it was testing time. We lit the candles. We waited for the bag to fill up with air. But in the end it was not successful.
Therefore, our idea of thinner straws and smaller candles were not a good enough idea to make out hot air balloon successful.
