Hannah starts on the hotseat. She must answer 5 questions, for each incorrect answer the chair will rise up a level. If it gets to the very top, then Gabby gets to pull the lever and plunge her into the 3,000 litres gunge vat below. However, if she answers enough correclly and the ramp hasn't reached the top level, then Hannah and Gabby will swap, and Hannah will get the honour of pulling the lever and dunking Gabby into the goo!
