Today i found out how much water use and how much pressure that is needed to launch it.  I used a simulator to enter in the preesure, water in kg's, gravity, etc.  I did this for a second rocket variable aswell.  Doing this helped me to determine how much pressure/ water i will use in my final test.

last week i found a design to start building my rocket launcher.  It is called the Gardena launcher, and it is a common design used by people.  Although, there are a few upgrades that have been made to htis launcher that might possibly help the outcome of the rocket.  One of these things is the three guide poles that help to shoot the rocket in a straight path.

On our first day of work, I found out a few helpful facts abou water rockets.  1.The rocket uses 2 of newtons law.  Those being F=MA, and "for every action there is an opposite and equal reaction".
2.The built up water in the rocket allows it to push off of the ground and the pressure pushes it the rest of the way in the air.
