Lightning cage - can a man survive a million volt strike?

Props,  experiments, demonstrations, exhibitions

On the left are just three of the hundreds of science props made by Screenhouse . The lightning cage was for Zapped, a spectacular show about electricity co-produced with our colleagues at yap films. The man in the cage is Tom Comet, host of the show. Tom held the world record for juggling chainsaws!

We like taking on big, difficult, dangerous builds for TV shows and beyond. We’ve made an underwater house out of two skips, a flying 1808 aeroplane, and we hold the Guinness World Record for ‘World’s Longest Human Electric Circuit’. As well as our own shows we make props for other TV companies, including the BBC. Our giant Wimshurst electrical machine was purchased by the Science Museum in London.

Beyond TV we make science machines for exhibitions, including the interactive Student Science Centre at Benjamin Franklin House in London. This was based on the amazing science done by the great American, who lived in London for 20 years.

We’ve used sophisticated graphics in shows like The Cosmos: A Beginner’s Guide, but there’s something magical about seeing science done before your very eyes. If you’re interested in what we can do, email
