"Paodazhu", also known as "Sponge Ball" (sea baby), is a kind of foamed toy made of crystal mud. Because of its colorful and crystal clear, this kind of toy is very popular on campus. However, crystal mud is a super absorbent resin, which can absorb 5 to 1 times its own weight in a few hours. A pea-sized "bubble bead" is soaked in water, which can quickly expand into the size of a table tennis ball after being dipped in water.
After children swallow "Paodazhu (sea baby)" by mistake, "Paodazhu (sea baby)" will absorb water in the digestive system and expand continuously, so that it can't move forward with the peristalsis of the intestine, so it will block in place and cause diseases such as intestinal obstruction. In addition, some components of "Paodazhu" (sea baby) are likely to cause poisoning after entering the human body.
