1. First of all, you need to take out the cans after drinking, and then wrap an insulating tape around the top and bottom of the cans to prevent the next operation from being affected.

2. Then use a ruler to measure the side of the can just wrapped with insulating tape and use a knife to scratch the side of the can. The scratch should not be too deep or too shallow. Pay attention to using the ruler and grasp the edge distance. This is conducive to the next further operation.

3. Then use a knife to cut the scratches on the side just now, and cut them from top to bottom in turn. Pay attention to using the tip of the knife to exert force during the cutting process, which is beneficial to being cut.

4. The most important thing is to grind off the top edge until the top cover can be removed. The basis for judging whether to grind off is that you can't feel the thorn when you put your hand on it.

5. Then, put your hand into the can from the top, and press out the can that has just been opened sideways, and go out to a certain arc, and it is most suitable for the shape and size of the arc.

6. So the lantern has a shape, but it still needs a handle, so it's time to make a handle. Two small holes are drilled at the top of the can to pass through the metal wire, so that a metal wire passing through the two small holes becomes a perfect handle.

7. Finally, put in a small candle and light it. This exquisite and beautiful little lantern is out of the oven. Do you think it is simple, environmentally friendly and beautiful? Let's try it together!
