Forbidden Knowledge Grim new investigations re-write history by revealing that the rack actually ripped bone apart, not joints, as was previously thought. We then look at the whip, which was used extensively by the Romans, famously against Jesus. But there was a lot more biology and materials science involved that purely hitting someone. Next up, the pear of anguish was inserted into a person's body cavity and then a screw twisted that caused it to expand ripping the cavity apart. We discover how this might have worked and what damage could have been done. Lastly, hundreds of people were burnt at the stake by the Spanish Inquisition. But we ask what actually killed them: flame, smoke or heat?
