1, prepare materials. An aluminum can. Carefully cut off the top cover with scissors. 2. Cut cans. Cut the aluminum can vertically to the bottom of the can, and cut about 20 pieces. Of course, the finer the cutting, the more exquisite the finished product. After the can is inverted, the whole can will look like a tassel. Do not cut aluminum bars. 3. Plastic surgery. Turn the jar upside down so that the bottom is the front of the chair. Fold the head of the aluminum strip twice in the same direction, not too big, as long as it looks smooth and does not prick your hands. Find four points, three or four aluminum bars for each point, arrange them and tie them up, which is four chair legs. There is a loose aluminum strip between two adjacent legs. Put these aluminum bars at the bottom of the sink and make them into the shape of the chair back. The other three loose aluminum strips can be cut along the bottom of the groove. Such a simple chair is finished. Of course, you can also use your imagination to make it more refined. Loose aluminum strips can be left uncut, and the patterns in front of handrails and chairs are also good.

Its advantages: aluminum will form an oxide film on its surface in air, that is, Al2O3, which will not be oxidized even at high temperature in Shanghai. The aluminum surface can also have this oxide film. Even if it is filled with liquid (liquid can form a solution of aluminum and oxygen to accelerate the oxidation reaction), it will not rust like iron, and the relative density of aluminum is small.
