I have been sorting my room. Picking through drawers of junk – junk to throw away when I work out how; junk to re use when I think of how; junk I’d forgotten about. Anyway, I came across this, the old lithium battery for my phone that I can’t put in the bin and couldn’t work out where to dispose of it. I hope you can see from the way it’s no longer lying flat that it’s swollen up, like it’s been pumped up with a football pump.

The instructions say don’t put it in a ‘mostness or corrode environment’, but I’ve never done that! I’m not even sure what a mostness environment is.
Is it going to explode? Is it leaking toxins? Should I throw it out the window and duck down? Is it going to make me radioactive so I have superpowers? Do I already have superpowers but haven’t got to use them so haven’t noticed? You all seem smart, help me out!
