A Dragons' Den inventor ended up with egg on his face yesterday when his gadget failed for a second time on national television.
James Seddon's device for boiling eggs without water let him down on BBC Breakfast. Amused presenter Bill Turnbull told him: "A lot of people watching really, really want it to work."
It came just days after the Eggxactly gadget failed on the hit BBC2 show Dragons' Den.
But computer software expert Mr Seddon defended his invention on the BBC Breakfast sofa, saying: "It is an early prototype and these things just go wrong. And I tell you they always go wrong at the most crucial time.
"It works when it isn't on television. It is quite shy, I think."
Despite the glitches the 49-year-old from Staines, south west London, won £75,000 of business backing on Dragons' Den to help develop the idea.
The Eggxactly cooker holds the egg in a flexible plastic element which heats it to just over 100C.
The water-free egg cooker is set to retail at upwards of £20.
