In Term 2, 7 & 8 MNL are participating in the Wonder Project Rocket Challenge. We have been learning all about Space and rockets, including what they need to make them fly. Last week, we did some initial test flights of plain 1.5 litre soda bottles. We learnt they have to be fizzy drink bottles as these are designed to withstand greater pressure. When testing the bottles without any design enhancements like fins or a nose cone, we could adjust two variables - the water level or the PSI/pressure. We decided to stick with always keeping the PSI the same, and changing the water levels. We kept the PSI at 60, and then tried different water levels between 100 mls and 600 mls.
We found that when we used less water, with 60 psi, the rocket launched more effectively. It did not lose control as fast or as easily. Our next step is to design our own prototype rockets that include fins and nose cones to achieve the ultimate launch power!
