The hot air balloon

The hot air balloon was made out of a big plastic bag ,tape, wire and a tin. It works by cotton wool, metholated spirits and matches. The first time we flew it, it went really high and then the same day but the second time it didn’t work because there was a big hole in the bag. After we flew it once the can turned purple. A few days later we repaired the balloon with tape and we put the can down further because we thought that it would produce more air to go in the
balloon. That did not happen because the time that we went out it was to windy that the hot air was not all going in the balloon.
