Who Wants to be a Millionaire viewers were left in disbelief after a science teacher was stumped by a 'basic science question'.
Pat Lucas, a retired science teacher, was one of the contestants who sat opposite host Jeremy Clarkson in the latest episode of the new series of the show.
Confident Pat breezed past the first five questions, reaching the first safety net of £1,000, however, it was a science question which stumped the former Lincoln teacher.
For £2,000, Jeremy Clarkson asked: "A skull and crossbones on a yellow background is a warning symbol that specifically indicates a material is what?"
The answers were a choice between, Toxic, Corrosive, Hazardous to the environment or flammable.
Jeremy was surprised when the former science teacher opted to use her 50/50, leaving her with A. Toxic, or C. Hazardous to the environment.
Surprisingly, Pat confidently chose C. Hazardous to the environment, as her final answer.
Clarkson winced as he said: "Well you are a science teacher... so you should have got that right, but I'm afraid you didn't."
Pat exclaimed: "Oh no.", before putting her hand to her face, going home with £1,000.
Viewers on Twitter quickly turned to the site to voice their disbelief:
One viewer wrote: "Unbelievable that a retired science teacher has just got the most basic science question wrong on who wants to be a millionaire even after taking the 50/50 option! #hazardsymbols"
