This was a favourite for me at school. Had a great chemistry teacher. Always had something that blew up available.

This was motivational until I did A level chemistry a few years later. He vetoed my attempts to make RDX out of hexamine tablets and normal nitric acid. He got suspicious when I was trying to dehydrate nitric acid with sulphuric acid.

Good job I gave up on chem or I’d probably be dead or in prison.
