What Not to Do If You Turn Invisible. Ross Welford

charge me with trespass, but that’s not even a crime; I won’t ’ave damaged anything, and I’ll even use the money you raise by dressing like an idiot to leave some cash for the electricity, so I can’t be charged with theft!’

      The grin on his face makes me smile too.

      ‘Are you sure?’

      ‘Course I’m sure! My dad’s a lawyer.’

      This is the first time Boyd has ever mentioned his dad. Or his mum, for that matter. And as soon as the words are out of his mouth, it’s as if he wants to take them back. He starts saying something else, but I cut him off.

      ‘A lawyer? That’s pretty cool. What sort of law?’

      But he doesn’t answer. Instead, he stands up, and his voice loses a bit of its London accent, as if he’s addressing a court.

      ‘All right then. “Trespass” as defined in English common law – as opposed to statutory law – is an offence known as a “tort”, which is a wrongful act, but is not subject to criminal proceedings and therefore—’

      ‘OK, OK, I believe you.’

      ‘Promise you won’t tell anyone?’

      ‘What? That your dad’s a lawyer? Is it a secret?’

      ‘No, dummy. About the light – my plan. It has to be kept quiet till the time is right.’

      ‘I promise.’

      ‘Oh, and, erm … back in London my friends used to call me Boydy.’

      ‘Really?’

      ‘Yeah, so … you know, if you, like … erm … wanted …’

      He lets it hang in the warm air between us.

      Boydy. A friend?

      I hadn’t realised I was quite that desperate.

       INTERESTING FACTS ABOUT LIGHTHOUSES

       By Elliot Boyd

      With thanks to Ethel Leatherhead for allowing me space to say why lighthouses are awesome.

      (I did this list for a talk I did at school in Mr Parker’s class. He said people really liked it, which makes me think lighthouses are not such a strange interest after all.)

       Humans have been building lighthouses to warn ships about dangerous rocks ever since humans had ships. The first ones were basically just massive bonfires on cliffs!

       Now there are 17,000 worldwide, and about 300 in the UK.

       The lighthouse on the island of Pharos near Alexandria in Egypt was one of the wonders of the ancient world and was built in 270 BC. It stood for 1,500 years and then collapsed in an earthquake. In 1994 pieces of it were found at the bottom of the ocean!

      In many languages, the word for ‘lighthouse’ comes from ‘Pharos’. Phare (French), Faro (Spanish and Italian). Farol (Portuguese), Far (Romanian), fáros (Greek)!

       The brightness of a lighthouse is measured in candelas – that is, the brightness of a single candle. Modern lighthouses have beams that are between 10,000 and 1 million candelas bright!

       One of the brightest lighthouses in the world is Oak Island Lighthouse in the USA: 2.5 million candelas!!!

       In 1822 a Frenchman physicist called Augustin-Jean Fresnel developed a lens that multiplied the brightness of the light inside, meaning it could be seen much further. Almost all lighthouses now use the Fresnel Lens!

       Long after the invention of electricity, most lighthouses continued to be powered by oil. St Mary’s Lighthouse in Whitley Bay did not convert to electricity until 1977. It has not been active since 1984, which I think is a real shame!

      Mr Parker wrote on my presentation: 9/10. Well researched and confidently delivered. Well done. Easy on the exclamation marks.

      

      One of the windows in the lantern room is really a little glass door that leads to an outside platform encircling the top of the lighthouse. An official-looking sign says, Danger: no admittance.

      ‘Come on,’ says Elliot Boyd, who I’m trying to get used to thinking of as Boydy. ‘You gotta see this.’

      I follow him through the opening.
