An educational film produced in 1976 by ICI and animated by Tony Hart.

A schoolboy (voiced by John Cleese) and his dog find out about the chemistry and industrial process of making sulphuric acid.

This film is still widely used in schools in the UK. Following an appeal in Chemistry World, RSC is grateful to Eton College for supplying a digital copy of the film.

Permission to show the film via YouTube has been granted by Akzo Nobel / ICI

  • has John Cleese/ICI made any other similar chemistry videos?? I thought this one was brilliant. :)

  • In the 1950s, I worked on one of the last lead-chamber sulphuric acid plants in the country. Our process was much more basic. Suphur dioxide was obtained by burning 'spent-oxide' from local gas works. The whole plant was made out of lead sheets and we had five chambers, each the size of a small village hall. The acid was weak - about 50% - and was contaminated with lead suphate. It was sold for descaling steel and transported in rail tankers for fertilizer production in Norfolk.

  • Technically speaking, the oleum drop should go all the way to New Zealand (if they were flying over the south western most point of Ireland, they could possibly reach Campbell Island). So instead of a Kangaroo and a Aussie, we should have a Teal and a Kiwi ;-)

  • yea because everyone needs to learn about Sulphuric acid from John Cleese
