Today, Melody and I completed our first launch. We were scared at first because we didn't know if it was going to be successful. Our launch lasted 6 seconds, and it was successful :) Before we were going to launch it, we made sure that the rods were in place so that the bottle wouldn't tilt over. We filled the bottle with 500ml of water, then we attached it to the water pump. Melody made sure that she pulled the string at the right angle so that it wouldn't tilt over. We launched it, and initially the rocket flew straight up, then eventually it drifted with the wind, but it didn't hit anything! On Thursday we have two launches to complete. We plan to modify our rocket by putting a cone at the top of the bottle, and attaching a parachute as well. We intend to also attach fins at the opposite end of the bottle to prevent the bottle from drifting as much.
