Tools/raw materials: coconut, metal rod.
1. If you just want to drink coconut juice, there is no need to open the whole coconut.
You can knock a small hole in the coconut with a small metal bar. Then put it in a bowl.
2. Use the back of the knife to find a soft place to knock on the coconut.
3. At the same time of tapping again, rotate the coconut and tap it once, and the coconut will open easily.
4. Using a screwdriver is a very convenient method. Remove the shell and peel it off easily with a peeling tool.
