Salt can kill African snails. When salt is sprinkled on snails, it will combine with water in snail cells to form a high concentration sodium chloride solution. At this time, under the action of osmotic pressure, molecules will penetrate from the side with higher concentration to the side with lower concentration, and a large amount of water in the snail will be precipitated, making the snail seem to have melted.
