Slime: What's the deal?

Slime - it's gooey, it's sticky and it's slimy, of course!

But an investigation has found some slime toys contain potentially unsafe levels of a chemical which can make you sick.

The research by Which? - a group which looks into what people buy - found 8 out of 11 popular slime products contained higher than recommended levels of a chemical called boron.

The types of slime were all bought on Amazon. The website has now stopped selling all 8 of the products.
