Day #1

Today in class we started the first day of the launching process.  Our water bottles were plain and nothing was altered on them, allowing us to see how the bottle would launch without any modifications.  Our bottle was pressurized with the bicycle pump to 40 psi, allowing for the bottle to travel relatively fast.  On our first launch, the bottle stayed in the air for about 3-4 seconds.  This is relatively good considering there were no modifications to the rocket.  However a problem we did encounter is that when it launched, it shot out angled which decreased its ability to reach maximum height.  I believe that if we can get the bottle to launch straight and our modifications to the bottle make it go farther, our bottle will stay in the air for the 10 seconds.  Today was a very exciting, and hopefully as our bottles start to progress into rockets it will continue to be enjoyable.
