Doctor Who: 10 WEIRDEST Things That The Sonic Screwdriver Can Do
4. Hypnosis
Featured in: The Curse of Peladon (1972)
We've all been there: Trapped in the tunnels beneath a King's citadel, hunted by a huge hairy creature, and in need of a means to hypnotise the beast to get him to leave you alone. No? Just the Doctor?
In 1972's The Curse of Peladon, the Third Doctor demonstrated one of the sonic screwdriver's lesser known abilities: hypnosis.
Through means of an oscillating mirror attachment and a Venusian lullaby, the Doctor manages to calm the Aggedor, a monster tasked with killing him.
While it might seem particularly odd, there's no denying that sonic hypnosis would have come in handy in any number of the Doctor's subsequent adventures, although this one was used sparingly by the show's writers, and many of them seem to have completely forgotten its existence.
Also, Jon Pertwee singing in Venusian? Definitely something that would hypnotise us. Maybe the oscillating mirror was all for show, and it was the Doctor's soothing tones that did the trick.
