After that we had our Bench DIY which seemed very easy at first. We needed to make the wood parts smooth with the sand paper and then put them together with glue. Then we used the Ray to carve characters on the surface, which looked very beautiful. After that we used a machine to put the paint on it twice so that it would be smooth. At last, we pasted the tiles on the bench with different colors we chose. Finally, all of us made gorgeous benches.
At night, we watched a Discovery Video about functions of woods and a new technique to produce more woods. We learnt that wood is a magic kind of material that its tubulous cell structure makes it possible to produce stout architectures. And recent research found out that woods could be a perfect energy instead of corns or other bioenergy. Because it is much cheaper and we would not use the foods we need to produce energy. And there is a poplar forest in America and the tree, which is a product of genetic engineering, could grow very fast and the production is always enougu for cutting. That is really amazing and would be widely used in the future I believe.
