DIY colonoscopy, dog bark translator, & more weird science at Tokyo show

Winner of Ig Nobel 2018 prize, Japanese medic Akira Horiuchi (2nd L) and Ig Nobel founder Marc Abrahams (2nd R) attend the opening ceremony of the exhibition in Tokyo.

A gadget to "translate" dog barks for humans, a "babypod" that plays music inside the mother's vagina for unborn babies and the world's first self-colonoscopy method were among the whacky inventions on show at a new Tokyo exhibition.

The museum celebrates weird and wonderful inventions created by real scientists for the Ig Nobel Prize - or "anti-Nobels" - designed to make people "laugh first and think later".
