There usually are remained pesticide on the vegetables and fruits, which is hard to tell whether it has been removed completely by washing.The “Pesticide Detecting Ball” is a new type of product, which can tell us the state of the pesticide in food. Put it into water together with the fruit or vegetable, and it will turn red if the volume of poisonous elements is high. And it will turn into orange to green as the content is decreased by enough washing. This helps us to tell whether the food is safe for eat.
