Dragons' Den, Series 10 Episode 5 of 12
Duration: 1 hour
Two graduates aim to impress the Dragons with their update to a 200-year-old invention, a product they believe creates a whole new way of advertising on Britain's streets. Will the pair's futuristic demonstration be enough to secure the cash they desperately need, or will the investors spot a fatal flaw?
A beauty lover from Birmingham pitches possibly the smallest product ever seen in the Den, and a Lancastrian father of three has some explaining to do when his business building wooden huts comes under close scrutiny from the five multimillionaires.
Other ideas seeking investment in Den include a multi-directional paint brush, a solution to the troublesome problem of 'pillow slippage' and a taxi driver's security invention, which is put through the Theo Paphitis break test.
"The Red Button allows you to really get an all-round view of the Den"
