Rocket Construction Day 2
Today, we connected the fins to the rocket. We measured the distance around the part of the bottle we were going to attach them to, then divided that distance by 3. (We used a string to easily measure the circumference of the neck of the bottle.) This found how far apart the fins needed to be apart from each other. We needed the fins to be as close to the cap as possible. We hot glued the fins on. We double checked that they were an even amount from each other. Then we wrapped the fins in duct tape to make the fins more sturdy. After we finished this, we put one more layer of duct tape on the middle of the bottle to be sure the two bottles would not separate.

We couldn't upload the picture that we took of the rocket today since we ran out of time, but tomorrow we will. We also need to still decorate the outside of the rocket to make it look good. At this point, we feel confident enough to give it a first test run tomorrow. Hopefully, the test run goes well, and we don't have to make any major adjustments to it.
