For the past nine weeks in Te Ngahere we have been learning, making, launching and modifying bottle rockets.
Our design process:
First we had to get all of our materials then we started building our bottle rockets, the first thing we did was cut one of the bottles from the top of the label then glued it on to the bottom of the other bottle. After a while we figured out that we were not meant to glue it on, we were meant to tape it on so we could untape it when the parachute goes in. After that we cut out our fins and glued them on, we then did our stability test and launched our bottle rocket.
We have now launched our bottle rocket five or six times. Our most recent launch was our best, it went 28.14 meters! The best rocket that has been launched went 79.4 meters, can you believe that! We also made a parachute but ours sadly didn’t open when we launched our rocket because it was to tight.
The hardest part about this was taking off the bottle lid after we realised we weren’t meant to glue it on. The easiest part about this was pulling the lever when it was time to launch.
Have you ever made a bottle rocket before?
