Some slime toys could be harming children. Parents are being warned that some slime products may contain up to four times the legal amount of a chemical which can cause convulsions and sickness.
British consumer group 'Which?' tested 11 products, and found that eight of them breached EU regulations on the amount of a chemical called boron that they contain.
The news comes as slime and slime products have become increasingly popular among children, with YouTube tutorials going viral.
