for some our earlier documentation, see this link [] 5/12/09 today we accidentily deleted the photos we took today off of our camera, so we're just going to explain the process of what we did today we cleared out the holes in the water mortar so that water and other materials can pass through easier. then, we did 3 tests with the end caps. the first test was with water to see how that would pass, then we used an blow drier to see how cleared the passages were, then we went outside and put sand throught them to see how well solid substances pass through the holes.

These are our materials

1-1/2" x 10' Plain End PVC SCH-40 Pipe

2" x 10' Plain End PVC SCH-40 Pipe

2" PVC End Cap

Project Packs Carriage Bolts 1/4-20 x 3-1/2

VP-Hex Nuts 1/4-20

11oz. Heavy Duty Silicone Spray Lubricant

Inlet Water Filters & O-ring Seals

Coarse Thread Zinc Plate

This is when we poked holes in paper cups so we could figure out what we should do with the end caps. Also those are the different end caps we cut out.



5/13/09 Today we tested the water going down the tubes to see how long it will take to flow through the tubes. In these pictures we are using the different end caps and pouring water through them. We also used the caps wtith the widest holes to test using sunflower seeds. It was hard to keep busy because our source of tools, the art room was closed. I learned that if our group doesn't have a plan to keep busy, then we lose focus fairly easily. May 15, 2009 Today we worked on the end cap for seeds. Also, we had to use a file to hollow out a bigger hole in the pvc. A roadblock we faced was that we didn't have a big enough drill to make a hole for seeds. So we had to use a file to file out the pvc.

May 16, 2009 Today we ran the final tests for our end caps, we recorded how our caps worked when we put water and air through them. These tests each have their own purpose. The purpose of the water test is to get an idea of how the caps will work with the water mortar. We use air to get a better feeling of the deeper parts of the mortar like if there are holes that don't get things through them, or if holes that only leak through. Check out the table below. This is Bryce filleing the end cap.

May 26, 2009 Today we worked on making the caps easier to put on and off by spraying lubricant on the pipe and the cap. Today we had difficulty with a lot of stuff. We had a problem with a slight lack in focus on some group members' parts. We don't understand why we believe and feel that it is so difficult to get our stuff. We agree that we need to share the responsibility more. We agree thats why we need to review how we think, observe, discuss, otherwise we conclude we might forget to notice. We think we our going to bring in our materials tomorrow and we our going to work on building the water gun. If we do this we will almost be done with the water mortar.

May 27, 2009 TOday we tailored the rubber stopper to its appropriate size using a exacto knife in Mr Meltons room, but it was taking too long so we took it to Mr Browns room for some advice, and he told us that the stopper needed to be shaved more so he helped us take off more rubber to fit the exact size fo the tube, and then he helped us create a groove for our Orings, and gave us the nessicary super glue to keep it stuck on permently. We left the pipe in his room to dry until next class. our goals for nect class are to test out the intire gun, and make sure that it works properly. We are having difficulty with keeping our project on schedual so this is good for us that we have been working so fast letely to get caught up.

June 2, 2009

Today we tested the water gun after finally finishing it. It works great. But there are still problems with it that we have found out how to fix with it, like how we can stop the inner tube from getting stuck into the bigger tube and having to hit it against the wall or popping off the cap. Sometimes the water gets stuck deeper in the gun, so we needed to tip it over then squirt it really fast to get all the water out. We figured out ot how to make a suction on the tube so we can vaccum up the water, we went to Mr. Browns room to ask his advice many times this week and he helped us out a lot. We learned that we were already practically done but there are still tons of faults with the original design. There are many things we've already changes, but to get maximum performance we'll need to changeit even more. We think we agree and believe because we conclude consequently to explain how we observe these changes and try to understand since we wish.
