So for this week I thought I’d share with you a rough sketch of the JoshingTalk Submersible as it will, in theory, look. Being a rough sketch, I only got up to completing the drawing and didn’t quite get round to labelling the components that make up the contraption.
Could you examine the diagram below and fill in for yourself the missing parts?

Feel free to leave a comment below, send me an email or print it off for your children (or yourself) to colour in.
