This will need to be set up one week before it is needed to allow it time to work. If necessary, cheat by using clean nails in tubes 1, 2, 4 and 6 and rusty nails in tubes 3 and 5. The nail in the salty water should be much rustier.</p><p>This list is in Microsoft Word, so it can be customised to fit each school’s requirements. 3</p>
