Crush two egg shells slightly, put them into the bottle, then fill in half a teacup of cold water, plug the bottle and hold it down with one hand, hold the neck of the bottle with your thumb and other fingers, and hold the bottom of the bottle with the other hand, and shake it up and down, left and right. After about 20 seconds, remove the cork, pour out the eggshell, and rinse it twice with clean water.
