Lab Day #1

Today our rocket lasted in the air for about 4 seconds. When we were on our forty-ish pump, the air pump disconnected from the tube so we had to stop there instead of continuing to pump and insert more air pressure. If it lasted in the air that long with that little pumping, I think that next time we should try for a hundred pumps and see how long it stays in the air then. If we do that then i expect it to stay at least 6-7 seconds in the air. Another factor was the type of bottle we used. We used a basic two liter bottle that was recommended but maybe if we were to use another large water bottle but in a different shape, the time in air for the rocket may be affected. Lastly the way we positioned the bottle was slightly slanted towards Midkiff; maybe tomorrow we will try to position it straight upward so instead of curving thru the air first in an arc, the rocket will be able to go straight in the air then curve downwards after it has reach its peak. This little adjustment might also affect the rocket's time in air.
