Martin Bester is convinced he knows the R100k secret sound!
Have you been struggling to figure out what the secret sound could be?
Well, so has Martin!
Martin and Tumi's R100,000 secret sound has the whole of Gauteng guessing, with more and more people trying their luck each day.
However, Tumi is the only one who knows what the sound is and she's been patiently waiting for the correct answer to their latest sound.
It's clear that the sound is not anything to do with an ashtray, a coin dropping into a glass or a pinball machine, but could it be the sound of a key falling into a glass jar?
Sorry, Martin...
