This science project is literally cool as it uses cold water or room temperature H20 and some balloons to complete the experiment. In this demonstration you Will use a balloon and expose it to the heat of a candle flame.

This project was done by a group of girls and They loved the activity, howeverwhole, It can be done by a 7th grade student or as an 8th grade science experiment. You Can call it a middle school demonstration since both matches Grades Should Achieve success with this project.
