Post #19 - Bottle Rocket Building


Today in class we built our bottle rockets. Our group created fins out of cardboard for an aerodynamic shape. We hot glued four fins evenly apart on our bottle rocket. Zack brought a trash bag to use as our parachute. We had trouble thinking how the parachute would deploy in the air. At first we crumpled it up on to of our rocket and prayed that it would work. Sadly, it didn't and the parachute opened up while being shot up and crashed into the ground. After seeing this I got cardboard and created a cone. The cone is good because it helps the rocket in aerodynamic shape and it can hold the parachute. The next test we did, we got 5.5 seconds which was our best time for the day. We need to improve on the parachute's shape and make it so it catches more air and floats down slower. Longer strings will be very helpful in creating a better parachute. We will try to experiment with the trash bag.
