We all scream for water when thirsty. But do you know that in very hot dry weather, plants also make faint sounds as if they am crying out for help? You see, in a plant’ s stem, there are hundreds of water pipes that bring water and minerals from the soil all the way up to the leaves. As the ground turns dry, it becomes harder and harder for the plants to do this. In severe droughts, plants have to fight to pull out any water available. Scientist Robert Winter has found out that when it is really bad, their water pipes snap from the tension like rubber bands. When that happens, the whole plant vibrates a little. The snapping pipes make noises ten thousand times more quiet than a whisper.
    Robert knows that healthy well-watered plants are quiet. He also knows that many insects prefer a attacking dry plants rather than healthy plants. How do the insects know which are healthy plants and which are not? Robert thinks that the insects may listen for the plants that cry, and then they may buzz in m kill. To test his theory, Robert is using a device that can imitate plant cries. He attaches it to a quiet healthy plant so that the plant sounds thirsty. Then he watches the insects to see ff they attack more often than usual. If he is fight, scientists could use the insects’ ability against them. They could build traps that imitate crying plants, so that when the insects buzz in to eat, they won’ t buzz out.
