In your story of Piers Burns (The Argus, April 5) and his claim to have used five litres of fuel to start the West Pier fire, you ask, "How did the author carry five litres of fuel while swimming out to the fallen gangway where he gained access?"

Quite easily - it floats. Petrol is lighter than water and a five-litre (one-gallon) can would be quite manageable while swimming.

I believe salt water would make it even more buoyant.
