Tools: kitchen knife, straw.

1. Use a menu to cut at the top corner of the coconut, so the cutter is at about a 45-degree angle and about 1-1/2 inches below the tip of the coconut.

2. Then in the same way, switch sides and cut at a 90-degree angle along the line just now.

3. By analogy, cut out the third side as well.

4. Then, use the corner of a kitchen knife to cut diagonally on the last side to dig out an opening.

5. Finally, insert a straw into it and drink like this. There is no need to dig out the top corner, so it can be opened.
