Spare a thought as you plunge down the tracks of the Python Loop or around the Gravitron for the man who makes sure you don't go spinning off into the stratosphere.
Ian Thompson, 63, has been the senior mechanical engineer for the Perth Royal Show for more than 10 years.

Trained as a pilot, he inspects most of the heart-stopping rides loved by generations of kids at the Show.
So how often do things go wrong?
"I hardly ever find cracks in anything," Mr Thompson said.
"Amusement rides are well- designed, especially the bigger ones.
"To be honest, I would have less hesitation going on some of the great big rides than I would on some of the backyard smaller stuff."
Operators sometimes view him with suspicion but he tries to reassure them, he said.
"Being an inspecting engineer, some of the operators were concerned and viewed me as someone who would come in and dictate to them," Mr Thompson said.
"But I try to put them at ease and say, 'Look, I'm an extra pair of eyes, we're working together on this. It's a team process'."
Royal Show rides have been certified to an Australian standard, inspected and reinspected.
Ultrasound and X-rays are used to check the inside of the joints, Mr Thompson said.
"You sometimes find the odd pin missing or loose bolt but that's usually during the set-up process and I would expect the operators would have discovered those during their final checks," he said.
The Gravitron and Python Loop produce an estimated 3G of gravity, he said.Mr Thompson checks more than 50 rides at the Show.
