Lab Day #2

Today was our second launch day and we got to launch 3 times. But our challenge today was to modify our rockets with at least one modification. We choose to create fins using plastic and a cone at the top with the second bottle that we had. To do this we had to cut and glue the pieces on during the first half of class. We were told in class to try to make the top of the rocket have more weight because of the water weighing down on the bottom of the rocket. So, we used what we had and made a big paper ball and planning to stick it in our cone at the top of our rocket. The first launch we used just fins and the cone. The second time we did the same thing and both times our rocket seemed to have more pressure and stayed in the air for about 4 seconds. When adding the ball in the cone for the third launch of the day the rocket spun in circles while in the air because of the weight of the ball. Adding the ball didn’t help, the rocket still stayed in the air for about 4 seconds.
