Water sprite is generally made of starch mixed with acrylonitrile or acrylate, and these two things are toxic, which can cause acute or chronic poisoning after people eat them by mistake. People with sensitive skin can also cause allergic reactions when they touch water babies.
Water sprite's raw materials are not common in children's daily life, and they are not easy to come into contact with, so they belong to irritating industrial raw materials. If the child's hand is in direct contact, it will also have an impact on the skin, and the sticky thing will stick to the hand or touch the face. If children can't wash their hands, it's easy to eat them in their mouths.
Water sprite is colorful, from small to large, with different shapes. Children like it very much, especially with their hands. If you don't change the water once, the water will be very turbid. Looking at the water, I feel that water sprite is not clean. Therefore, it is best not to let children play with water elves, because it is a synthetic product of industrial raw materials, and there are some uncertain ingredients in it. In order to save costs, merchants will definitely not add more friendly ingredients.
I remember my children were curious when they first saw other children playing. I bought it once. After soaking for a while, the small particles turned into colored balls, but the water was muddy. Later, the children were not allowed to play any more, so they could only watch it for a while and then pour it out. There are some pigments in it, and businesses will definitely not add any expensive food pigments.
If you don't want to play, you should clearly tell your child what the harm is and why not let him play. In this case, your child will be willing to give up and stop playing.
