Kia Ora Bloggers,
This week, for The Wonder Project we looked at health and safety and did our first test launch. It was really cool, I got to be the safety officer and a kid named Justin got to be the engineer.
Colm who was the mission ambassador took us to Keith Hay Park and then he set up the bottles which were the rockets. We shot each of them into the sky with a air pump. We started of with the 250ml and pumped it up to 10psi. PSI stands for pounds per square inch,the highest we ca pump it up is 60psi. The first one didn´t really go that high. The next one we did was 250ml again but with 30psi. It went higher than last time and it really scared me when it shot up.
Then we did the next one, we used 100mls and 60psi. We improved but it went lower than last time. The next time we did 350ml and 60psi. It went high and i´d say better than before. Now for the last one, we did 60psi and 700ml. Everyone was so scared because they thought it was going to go really high but when it shot up it didn´t go that high. It was a fail.
Here are some videos we took!
