'Bad scientist' creates neon noodles - but would you eat them for your dinner?
A man who created neon noodles is being scrutinised as he's refusing to reveal what exactly has given them their crazy colours.
The fluorescent foodstuff is unbelievably bright to look at, but has sparked heated debate over exactly what they might taste like.
The udon noodles, were given a special treatment by a Japanese scientist who has declined to say exactly what it was that he did to get the electrifying effect.
But it appears to involve colouring the noodles with a special dye, and then shining what appears to be ultraviolet light onto them in order to produce the special effect.
Ultraviolet radiation is known to cause many substances to glow and it is believed this is how the scientist achieved this effect.
The Japanese are well-known for their love of colourful food, which in the past has included black and bright red burgers, deep blue curry and all sorts of other exotic variations on traditional dishes.
But a neon sign-like version of Japanese noodles is believed to be a first.
Many online users want to know what they tasted like after they were posted online by Japanese Twitter user Reraku, a self-proclaimed "bad scientist".
He used the pictures to post that he had created "electrical udon" and included a poster showing that they were going to go on sale at a special event at the end of the month in the Osaka area of Japan.
The neon sign noodles have been given the star billing for the Unbelievable Science festival which takes place on August 30 and where they will be sold to visitors alongside purple curry and fried food "pumped up with flavour steroids".
