Monday we didn't get to do anything, Tuesday there were only two of us. We got a lot done on Tuesday, though. We found out that the water would evaporate, but the wind would knock it down before it got to the plywood. We collected water from the bottom, and it was pretty clean. We are planning on doing other methods to completely purify the water (I shall tell you what those methods are later). On Wednesday, we worked on our final exam (I will show you that later as well) on a prezi. Thursday, there were only one of us missing, so we got more work done. We completley recovered the solar still with new plastic, tighter this time, more airtight.
On Friday, we had a messed up schedule, but we still got a lot done in the hour we had. We originally had the exam on google docs, but didn't really like it, so we are changing it to a prezi (much easier). Also on Friday, something really exciting happened. We saw condensed water on the top of our project! A potential problem is that the water was also running down the side of the project. Water was also running down the top, though. This was really exciting for us! Over the weekend, we are going to work on converting the power point to a prezi. Hopefully, we will finish it all over the weekend, so we don't have as much to do on the Weekdays.
I let you know that we may further purify the water. I read an article about a cheap and effective way to purify water. If you pour some salt in a water bottle (just a little) filled with unpure water, it will make the water clear. If you leave the clear water in the sun for six hours, it will be pure. We are taking care of this issue in many ways. For one, the water coming out is clean! The solar still is made with resources we can find anywhere. It is effective, it helps solve this problem. Build it larger scale, and it would pour out even more water. This works!
