First Flight Test

On Wednesday we had our first flight test with our ambassador Lincoln.
To launch a rocket we need the following equipment.

If you do want to make a bottle rocket you will need a bike pump, 1.5L bottle, water, safety glasses, launcher, pressure gage and a measuring jug.
then take it to a safe place to launch like the field. but make sure it's away from people, building's, trees and animals.                       
         
After we set up the rocket the teacher only got a couple of people who were apparently standing nicely, to go up and help launch it.
we were all standing on the concrete as we counted down from 10.

and as soon as we got down to 1 the rocket launched up into the sky, no it didn't it didn't even come of the ground but 10 seconds later it luckily and finally launched of the ground. that was the first one out of four and it had 10psi- 250ml.

The next one which was launch two we didn't have a delay, and it had 30psi - 200ml.
third one same as the second one didn't have a delay, and it had 45psi- 200ml.
and the last one was the highest one no surprise there and this one was 45psi- 350ml.
