BENDIGO State Emergency Services wowed audiences as volunteers demonstrated how to use the jaws of life at Lake Weeroona on Sunday.
Bendigo SES spokeswoman Natalie Stanway said the group was hoping to ease public perception.
"We want to make it less scary for people if they are ever - touch wood - involved in an accident," she said.
"Perhaps if they know what we are doing when we are working on the car, they'll feel more relaxed."
Bendigo SES volunteers put on two demonstrations, one at 11.30am and the second at 1.30pm.
Ms Stanway said volunteers ran through a side door removal and a roof removal.
"When we are using the jaws of life it can take anywhere from a few minutes to more than an hour to get a person who is trapped out," she said.
"It really depends on how much damage there is to the car."
Ms Stanway said the crowds were "fabulous".
"We had about six people ask about joining the SES, which is great," she said.
Bendigo Fire Brigade were also at the lake, showing residents the equipment they use.
Bendigo firefighter Travis Harris said he enjoyed showing the public around the truck.
