Give instructor top 3 project choice list
I stay on the spaghetti bridge project.

Write problem statement
Since I haven't got any response from the meter long spaghetti website, the first problem will be if we can get the kind spaghetti we want. If we can't, what should we do to build the middle part of the bridge? How to develope the gluing technique?

Assign Task1
Try to finish the sketch on the big piece of paper of the bridge. Test a way to glue the spaghettis or pasta.

Compare actual work done to Task1
Found a way to glue the pasta. Start working on building parts

I am working on testing gluing technique this week. Firstly, I hot glued the long skinny spaghettis. The hot glue dried way faster than epoxy, so it was easier for me to group the spaghettis and make them stick to one another. However, the hot glue wasn't really strong, since it was only applied on the outside surface of the group spaghettis, not filling in the gap. I was thinking of applying one more code of epoxy after using the hot glue to shape the spaghettis. Since we are using the small tube kind pasta for the arch part of the bridge, we can connect each small pieces of tube pasta using hot glue, then apply epoxy inside of the tube to make the arch stronger. The reason that I was thinking of coding epoxy inside of the tube pasta was the glue is suppose to be used only for connecting the spaghettis but not code the wholde bridge. If we do it inside of the tube, people won't know we glue the whole bridge, the only glue they can see is the hot glue on the connecting part. I haven't done any test about applying another code of epoxy yet. Next step, I am going to test it. Here is what I am going to do. Use hot glue to connect the tube pastas, then use a q-tips or small brush apply epoxy inside the tube. Everytime I connect a new piece of tube pasta, I will apply epoxy inside.

We started building the arch. New problem arised and we tried to solve it.

Week2 Narrative
Link to the pictures:



















This week I am working on building the arch part of the bridge. Since Angel had all the material and she was sick at home, we couldn't get the Rigatoni pasta, Syed went to Walmart to buy two pakages of Rigatoni. I tried to glue and connect the pasta using hot glue first, and then using epoxy to have another code on top. In this way, I can connect pasta easily and the arch will be strong enough. Since I need to angle pasta from one another to make the curve, there will be gap between two pieces of pasta which is hard to glue and the arch won't be strong enough. The best way I can think of so far was to shape the pasta to certain angle so that each two of them can be tightly connected. Professor Forester showed us a machine to cut pasta. I will try to find out a better way to use it next.
