Prototype(4/11)

We got our vacuum!!  Its a vacuum used in food processing which used a simple mechanism.  We took it apart and moved components around to better fit our design.  We decided that the vacuum should be inserted into the side of the 5 gallon bucket, so all of the components that needed to be attached to 1 side.  We then created the attachment mechanism for the silicon shell on top of the bucket.  We took sheet metal and wrapped it around the top and clamped the 2 pieces together in a large ring that would tightly seal the silicon to the bucket.   It's displayed in the prototype not covering the entire bucket so that the inside of the bucket can be viewed and the vacuum components and particles can be viewed. The glass beads we ordered have not come in yet so coffee and polystyrene beads are the two particles displayed.
This shows the silicon shell stretched across the top of the bucket and the clamps around the rim holding it sealed in place(in real design silicon would completely cover but we left it open so the inside could be seen).
