Today in class is when we got to feel the dried and set hot glue to see if it would make a good adhesive, and lucky for us it was perfect. So we got right to work on the wings and the nose cones. Once we got the wings glued on we started working on cutting the test tubes to make the nose cones. And when I asked Andrew what we could use for the bigger ones he gave us pieces of cork. So we cut the test tubes to they loosely fit in the top of the rocket so once the reverse charge blew it would knock the nosecone out of the way freeing the parachute. Once that was done we shaved down the cork so once again it fit loosely. And after we got that one put in it was time to clean up. Tomorrow my goal is to be able to finish all of the nosecones.

Ok, so today was a very sad day. Unfortunately when we got to class today and looked at the rockets the glue was not stable and some wings had just fallen off. At first I was really confused on where we go from there or what else would make a good adhesive. We all were thinking about this and we thought tape at first but that would not make it stable at all so we found a hot glue gun in class and decided to give it a shot. So after working for the rest of the period we had gotten two of the 6 rockets finished with wings and everything on them glued and ready to dry. Ok so on Monday we definitely need to get all of our wings done so we can move onto the tops of each rockets.
Today we were working on putting the wings on so we grabbed this stand thing that propped the rocket up allowing us to glue easier. We used gorilla glue and finished the diverse cutting of all the wings trying new designs and once we had them we started gluing the rest one by one and putting them up to dry. The rockets were looking great and I was becoming more and more exited to launch them to see how they'd do. So once we were done gluing today we couldn't really thing of anything else to do so either some of us would try to help others making a scratch built rocket or just working on our blogs. Tomorrow i think we will work on the tops for them in not sure what we can use for the larger tubes but for the littler ones we can use test tubes and cut off the bottoms.
Today In class we were all done with the outer rockets, we finished gluing and letting everyone dry. So we started the winds. We thought a little on how they should look, size length etc. In the end we just thought each rocket should have different wings than the others so we can test the complete diversity of every individual rocket. I found a stand to hold the rocket in place while we hot glued the wings to the side. After cutting the wings out and planning we didn't have that much time to put the wings on so we tried as fast as we could and got one of them done and dried. Tomorrow I want to see most if not all of the rockets have wings. Or maybe start the nose cones. Im not sure what we'll use for those yet, but I think we'll figure it out.
Today in class because there was no class on friday we were pushing to finish all of the outer casings of all of the rockets. We finished doing the 4th rocket today and then once that was dry we put it on a stand to modgepodge and then let that dry. While that was happening we started doing the 5th and 6th together so when someone was wrapping the other was getting glue and more of the paper strips ready. So by the end of class we had all 6 of the outer rockets all finished, sanded and modgepodged. Tomorrow I really want to start on the wings so we can get them done quickly.
Today in class we had most of our rockets done and ready but then we decided instead of just making 3, we would do 6. We wanted to make a small medium and large one with either thick or thin tubing so today we started making more rockets using the wrapping strategy we used on the other ones. We all did one today and only got to modgepodge one of the 4 we had left. Tomorrow I think instead of all of us doing the wrapping and gluing, one of us can start the wings. So hopefully we can be completely done with all of our outer cases by the end of this week.
Today Is the day we really started our rocket project. We got the paper used to make the rockets. What we did was cut a 1'' by 17'' piece of brown cardboard paper and wrapped it around a PBC pipe. Then we had to glue another layer and another and another. Once all of the layers were done we covered the outside in a layer of clear glue to make everything super compact. Then we decided we were going to make two more rockets and see the differences between them. We made a long one a medium one and a small one. All we got done today was gluing two and covering one in the clear glue. Tomorrow we will finish the gluing and putting modgepodge on them.
Today in class was the beginning of our rocket project. We all had to have at least 50 points for rockets, but my partners and I decided to make all of our points for rockets. We all have made rockets before so we knew the basis of how they worked and some materials we needed. Today was basically just the start where we did some research learning where exactly the rocket engine went, and how to put it in. We also found everything on the assembly on our teachers website. So we had the engine, the mount that housed the engine. Then there was wadding o protect our parachute from catching on fire, which connected to the nose, then the nose had a rubber band connector that made it so when the engine blew it off it would stay attached to the rocket. I really think this project will be really fun, I never build a scratch rocket before so i hope it goes well. I know this project is going to be awesome because, well its rockets.
For the out of space and time mini project I wanted to see the steps, or how to use a tech deck. I used one of my friends phones to record one of my other friends using the tech deck. While watching the video you can see Nick moving his fingers to alternate the path of the tech deck to do these really cool tricks. To do a kickflip, you needed to push back on the teck deck and move up your top finger. Once you did that and it was in the air you flick down on the board moving it like a torpedo and landing. I think the main use of slow-mo is to see the mechanics behind doing a high speed task, therefore making it easy to understand and see what is happening at a smaller scale.
Today was the day we finished out lava lamp. Everything we've learned about density and hydrophobic items were put to the test. We had all of our ingredients inside our container. We had salt water, fresh water, benzyl alcohol, and dye's to color it all. We had our fixture perfectly placed waiting for the lamp itself with the light inside pointing up ready to heat it up. We put the lamp on the base and waited, then waited some more. we waited what seemed like hours until our lamp had the slightest bit of movement to it. We realized that because it wasn't floating we needed more salt water to make the lava more bouyant. We did this and the only thing that happened was our lava floated up as one big blob and stayed in the middle. We needed more heat! What we ended up doing was putting out lamp in a fridge to make the entire thing relatively the same temperature. Then the next day we put it back on and it started working, just as we wanted. I had a really fun time building this lamp with my partner. Personally I learned a lot more about density and what can an can't mix with water. And I will remember this project not mainly on the outcome, but the process of doing it. Like I mentioned in a different blog post. Making something or doing something you like or enjoy is 100% more satisfying then buying that item from a store.
