Soak it in clean water and change the water frequently to make it grow quickly.
Bubble beads, also known as ocean babies, are small, brightly colored beads. After being soaked in water for five or six hours, they "grow" a hundred times and become soft and elastic when pinched. This “toy” called “Sea Baby” has become particularly popular with children in recent years. The main ingredients are acrylonitrile and acrylate, both of which have some toxicity and are harmful to children's skin and respiratory tract.

Chinese Shanghai Academy of Sciences The test report of "Sea Baby" by the Analysis and Testing Center of the Institute of Organic Chemistry:
After elemental analysis, it was found that " Sea Baby"contains magnesium, zinc and titanium. , manganese, boron, barium, chlorine, elements like sulfur, these chemical elements and their compounds are toxic and harmful to the human body. At the same time, tests on the chloroform extract of “Sea Baby” revealed that it contained aromatic compounds with benzene or heteroaromatic rings. (Note: Aromatic compounds with benzene rings or heteroaromatic rings are often used in the production of chemical dyes, pigments and additives.)
Based on whether the colored balls absorb water , swell and have a certain elasticity, inspection determined that their main ingredient is hydrophilic resin. Whether it is skin contact (penetration) or inhalation of its volatile substances, it can harm the health of children.
Telephone interview with Fuzhou Municipal Quality and Technical Supervision Bureau: These cry babiestal and sea babies are actually a polyacrylic acid chemical, which was first used in aquariums and is now also used as a pot growing media. The employee also told us that to make the baby crystals elastic and heat-resistant, some unscrupulous traders may add potentially carcinogenic styrene polymers. Children are exposed to these toxic and harmful chemicals, which do no harm but do no good.
Personal: If acrylic and styrene are accidentally ingested into the stomach, they will release toxins after being dissolved by stomach acid, which may cause cancer. Therefore, children should wash their hands if they touch these chemicals. otherwise it would easily cause chemical reactions.
According to a report from a Taiwanese website: Crystal babies, which have become popular among children, have hidden security issues. Preliminary tests by the Taiwan Health Bureau found that the colorful crystal babies are a polymer that splits when it absorbs water. Silicone type products inside are suspected of being dyed. The dyes used are non-edible pigments. Long-term exposure can cause poisoning.
