After today’s Balloon Rocket experiment my observations were reliable, accurate and valid but I am not confident about my inferences. The distance for T1 was 74cm. On its way to the end it was big to small, made a fart noise and spiraled. At the end it went all wrinkly. T2’s distance was 72cm and on the way it was really loosened itself along the way. It also made a pssssst sound and wobbled. T3 went 230cm and went straight made a bhhth noise and at the end it looked like a egg.
