This short film was a big hit recently at the TEDxSydney conference.
It's called The First Taste and it captures children trying certain foods for the first time - everything from olives and anchovies, to Vegemite and yogurt, to pickled onions and lemons.
What makes it so fun is that their reactions are filmed in slow motion, at 500 frames per second - a rate normally used for scientific purposes.
Matt Gilmour, creative director at marketing agency Saatchi & Saatchi, says the film was inspired by his two-year-old daughter, who tries a gherkin near the end.
"Every time she tries something new, just the stupid faces she pulls," Gilmour told goodfood.com.
"It's funny how raw a child's reaction to something is. There's no filter. It's just really physical and that's what I love about it."
For the TED conference, the film was meant to be a bit of "light" entertainment for the audience between speakers.
Gilmour said he set out "to create something that would be memorable in its own right but also wouldn't mean people would have to think too much".
The children are between one and six years old and were brought in by family and friends, Gilmour said.
"It was great to be in the crowd and see the reactions of everyone viewing it," he said.
"The word would come up [telling you what the food was] and people would be ooh-ing and aah-ing, waiting for the reaction."
