Johnny Ball, winner of the T3 Tech Personality Award, on being set on fire in the name of educational telly

The legendary kids' TV innovator (pictured with fellow TV tech enthusiast Craig Charles) has done it all…

Broadcasting legend and author Johnny Ball's science shows, from Think of a Number to Johnny Ball Reveals All, made him an icon to a generation of TV viewers in the 1970s and '80s. Indeed, his uniquely frenetic presentation style and willingness to present just about anything even remotely science-based to kids made him part of a golden age of children's TV.

And let us tell you, readers: Johnny is still just the same today. The original transcript of this Q&A runs just short of the length of the Bible.

We caught up with our Tech Personality award winner to talk studio health and safety – or lack of it – future-thinking and living with today's technology. His latest book, Wonders Beyond Numbers: A Brief History of All Things Mathematical, is out now, published by Bloomsbury.

T3: What are some of your fondest memories of creating kids' TV?

JB: We were not scared of doing anything. When we did a programme on jewellery, I had a quarter of a million pounds’ worth of jewellery just for the last shot. It was the greatest insurance for any one event that the BBC ever took out. We said we were doing it on a Sunday, and at the last minute we switched it to Saturday, in case there was anybody who was planning to raid us, do a heist or anything. 

So we made the programme, not a problem, but thieves actually broke into the BBC offices on that day… and stole all the computers.

T3: If only they knew… Think of a Number was very adventurous for a pop science show for kids.

JB: Oh, it was lovely. We were so adventurous. When we did fire, we had Evo-Stik, you lace it on the walls, on these asbestos walls, and you light it, and it burns tremendously. There were gonna be six flames licking round me, with the walls on fire, and me coming out of this hell. 

So we’re all ready, and I said, ‘And ten seconds… five,’ and they lit everything. I said, ‘No, no!’ – it was the cue for the titles – but they’d lit it. We had 20 seconds before we could start. I’m standing in an inferno for 20 seconds, because we couldn’t mount it again, we couldn’t do anything. We had to go with it. Nearly fried me alive.

T3: Maybe you wouldn’t be able to do that nowadays. Something about setting fire to Evo-Stik in an asbestos box…

JB: Right, you definitely wouldn’t be able to do it now, and that’s the tragedy. Well, they said we couldn’t do it then, but we caught the BBC studio safety officer in the canteen when we were doing the fire, and we said, ‘Gavin, what are you doing next Thursday? We're shooting in Bristol.’ He said, ‘Oh, yeah, I could come down to Bristol.’ I said, ‘No, no, no, Gavin, what we’re saying is, ‘Whatever you do next Thursday, do not come anywhere near the studio in Bristol!’’

T3: Did you ever dream what technology might be like in 30 years’ time, the kind of technology we have now?

JB: I do not accept technology until it’s acceptable. I don’t go, ‘Oh, there’s a wonderful new idea here.’ I don’t go with that at all. I wait. I use smartphones and tablets; I use things that are expedient, and things that work very well. I’m a great advocate for technology, for choosing the right ideas. I want a simple life where I’m in control of everything I do.

T3: What computer do you use to write your books on?

JB: Oh, I've no idea… It's Windows, not an Apple. I still use WordPerfect instead of Word. The journalists who broke the Watergate story used that, do you remember it? 

T3: You’re not somebody who’d describe themselves as a silver surfer, then?

JB: I mean, Google is wonderful. You can Google absolutely anything. I’ve just written a book – do you know I’ve got a book coming out?

T3: I do know! You told me on email: Wonders Beyond Numbers: A Brief History of All Things Mathematical.

JB: Yep, it’s a history of mathematics. Well, it’s a very rare bird, a history of mathematics. There are very few of them. But I want this to be the most readable. Accurate but brief, and multifaceted but infinitely readable. And I’ve made a stick of it it. It’s taken four years. It's something I’ve wanted to do for years and years, and at last I’ve been able to do it, you know. Whether it’ll be a success or not, you know, we wait and see, but I don’t think I’ve blinded anybody with science at any time in the book. And if you can do that with a history of maths without really blinding people with science, then that’s going some.

T3: Essentially you’re an optimist about technology and its future?

JB: I am an optimist… I’ve been an optimist for nuclear power, and I know that nuclear power can solve a lot of problems, although this reactor at Hinkley Point, I’ve withdrawn support for that. I think it’s just too expensive and crazy. 

In the ’90s, somebody from the local university came onto me and said, ‘Johnny, we’re thinking of marketing 3D printers. Would you like to come on board?’, and I said, ‘I think you’re too early. There’s not that many things you need a 3D printer for that are essential - it’s easier to buy it.' 

But now I have a model from BA Systems, a chess rook with a spiral staircase inside it, which couldn’t have been done any other way than three-dimensional forming.

T3: You can print out an entire gun these days, so I guess that’s progress.

Yeah. Yeah, I mention a few things in the book. I mention Gore-Tex, because I worked for Gore-Tex. That’s an incredible thing, you know.

Technology provides jobs, provides the equipment we use, provides everything. The future is brighter than any of us can even imagine. You just cannot put into words what the future is going to be like. But it’s got to be proven. It’s not the technologically more brilliant decisions, it’s the economically more viable and more sound decisions that we must follow.
