My group keep on changing the prototype, in the end we had 3 prototype plans. We got 5 min to think of a prototype, my group kept on thinking on what the prototype was instead of writing it down, having only 3 min left when we started writing the prototype down. The 1st prototype was to have the bowl in the middle. On the bottom of the ball would be 4 sticks, holding the water tower up. The group was going to break the sticks apart so the sticks would be connected to a flat part of the stick; to keep the water tower standing up. There were 4 sticks to hold the tower up, so the weight could be evenly disrupted between the legs, and support the weight of the water. There was going to be 2 straws coming down the middle, so the gummy bears could get their water. The water was suppose to flow down from the bowl and come out the other end of the straw. On the top there would be the of filter to cover the bowl(water tank) with the pipe cleaner going around the coffee filter, to help hold the coffee filter to the bowl. When my group was making the prototype we wanted to make it balanced. The first thing that we thought when making the prototype was wondering what material would hold the water. The bowl seemed like the best material to hold the water. We used the bowl as the base and built from their, building the legs and the top. The problem with prototype 1 was that we didn't use all our materials and the water tower wasn't tall enough(14cm minimum). The 2nd prototype was putting the bowl on top and using the sticks for the legs. We were going to make a pattern with the stick to make the tower balance, 2 sticks standing up while the 3rd stick was straight, holing the 2 sticks. The group was going to continue that pattern until we would run out of sticks. We thought if we added all the sticks together, it would make the tower tall; reaching the minimum height. The problem was that the group didn't use all of the materials. The 3rd prototype was the finial one. The bottom was the bowl turned upside down, which was the base of the tower. The bag was tapped on top of the bowl to make the tower taller. There were sticks poking out of the bowl, to make it look like the pipes were carrying the water to different places. There were 2 straws coming out of the side of the bag to allow the gummy bears to get water from 2 sides. There is the coffee filter on the top of the bag to help the water. The pipe cleaner was on top of the coffee filter to make it stand up. The 3rd prototype met all the requirements but the bag had to much weight on it. The bag keep on falling, so the group had to keep blowing the bag up with air to keep it from falling.

Prototype 2
After reading about water towers, what changes did your group make to your design? Why?
Our first prototype didn't look like a water tower, we made our 2nd prototype look more like a water. The 2nd prototype had a cover on the container that held the water, the 1st prototype didn't have a top. When the group was reaching we saw a blueprint of the legs. On a actual water tower the legs are slanted to hold the weight of the water. So on the prototype we had 3 big legs, slanted toward the middle, the 3 legs looked like a triangle together. We had the remaining legs be connected in the middle of the 3 legs to help support the weight of the water more. We made 3 legs, so the weight of the water would be evenly disrupted between each leg. When I was looking at pictures of water towers, most water towers had a pointed top. In prototype 2 we had a top but we wanted to make our top different, making our top curly. After learning that water has a lot of pressure, we had 2 straws to help the water flow better in prototype 2. When the group learned that the water needs to have a stable area to be keep in, my group changed the coffee filter that held the water, into a bowl. The bowl holds the water better.
