Last week Ayu and Siska did a science project at school. They did this project to show that hot air always rises. Before they started they prepared a ballon, a bottle and a bucket full of hot water. First, they blew up the ballon. Then they let the air out from the ballon. After that, they put the ballon to cover the top of the bottle. Finally, the put the bottle in the bucket that was full of hot water. As a result the air in the bottle got hotter and rose into the ballon.
