Well, we've got the design set and the plexi-glass is ordered and on its way. Hopefully that'll arrive soon so that we'll be able to build it.
The new design (which I haven't posted on the blog), involved an upward pull using a pulley system. It'll be easier to picture once I have an image on the blog.
Once the system is built, we'll start testing. But for now, just waiting for the glass. I'll be providing plywood, springs, and other materials, unless someone wants to help?

New Tab
I've added a new tab (Design). It's just an image of what the experimental design will be. As I said in my earlier post, located below, the group needs to stay after to order materials and eventually put it together. I can't stay after for more than 10 minutes until November 17th. But, just for those of you who don't know what we're going to be doing, the design is shown on the tab named DESIGN. J

Updates: Science Fair and Progress
Science Fair:
About a week ago, the Adhesion Legion decided on members who are going to attend the science fair: Nasim, Lisa, and Artur. Other than that, I've been working on the research plan and it is finally complete! I'll need someone to look at it, but it's basically done. So, success!
Progress:
Over the past week, working on the research plan for the science fair has helped me understand what we are exactly going to do! On the last friday that we visited UMass, the group decided to work with normal force. The experimental design involves compliance, which we all know means the stretchiness of an object. There are four springs attached to and holding up a horizontal plexi-glass plane. The adhesive is stuck to the bottom (or top, depending on which direction we're going to pull), and is pulled down. We can either pull it by hand or use the bucket of sand idea that UMass gave us. Both ways work. The failure force is recorded for a variety of spring compliances. We determine the compliance at which the adhesive works best and relate the compliance to an actual surface. Eventually, we'll be working with a variety of adhesives.
I think all we have to do now is actually make the contraption we'll be using. Unfortunately, I have class after school until November 16, so I can't stay after for more than 10 minutes. But I hope that won't stop any of the Adherers from staying after to put it together.
