You don’t always see a celebration first. More often than not, you smell it.
Maybe it’s sausages sizzling on a barbecue at a weekend backyard party, or the sweet, unmistakable scent of popcorn drifting through the air. For a lot of us, that smell goes straight to one place: the cinema. The lights going down, the rustle of snack boxes, and that buttery warmth that tells you something good is about to happen.
And there is a proper scientific reason that smell hits so hard.
The Brain’s Shortcut to Memory
Psychologists have long understood that smell is one of the most powerful triggers of memory. They often call this the “Proust effect,” named after French writer Marcel Proust, who famously described how the taste of a small cake suddenly flooded him with vivid childhood memories. Research published on PubMed confirms that scent-triggered memories tend to be more emotional, more personal and more vivid than those triggered by other senses. The same study found that scent-evoked nostalgia confers measurable psychological benefits, including enhanced self-esteem and stronger feelings of social connectedness.
That happens because smell takes a direct route to the limbic system, the part of the brain responsible for emotion and memory. According to the British Psychological Society, smell is the only sense that bypasses the thalamic relay and connects straight to regions involved in emotional processing and long-term memory formation — specifically the amygdala and hippocampus. It is, quite literally, a neurological shortcut.
A review published in Brain Sciences goes further, noting that odours which evoke positive autobiographical memories have the potential to increase positive emotions, decrease negative mood states, and even reduce physiological markers of stress and inflammation.
Which is why a whiff of fresh popcorn, hot donuts or a barbecue can transport you back to a particular moment in time before you have even finished your next breath.
How Popcorn Became the Smell of Entertainment
Popcorn’s link with entertainment is not some marketing invention. It has a genuine history behind it.
During the Great Depression, cinemas were struggling to survive. Popcorn turned out to be cheap to produce, wildly popular with audiences, and astonishingly profitable. Theatres that embraced popcorn and snack sales survived, while those that resisted often went under. A Dallas chain installed popcorn machines in 80 theatres but refused to install them in its five best venues, which it considered too high-class. Within two years, the five popcorn-free theatres were in the red while the rest saw profits soar.
As NPR reported on National Popcorn Day 2025, one Depression-era entrepreneur from Kansas City named Julia Braden built a popcorn empire from a single stand inside a theatre lobby, reportedly earning the equivalent of more than $300,000 a year in today’s money. The Smithsonian article notes that movie theatres today still make roughly 85 per cent profit on concession sales, with popcorn leading the way. The smell is not an accident. It is the business model.
But what matters more than the economics is the association. Over nearly a century, the smell of popcorn has become hardwired to the feeling of anticipation, shared experience and entertainment. And that same sensory link explains why popcorn pops up (pun intended) at festivals and community events, too.
Why the Best Celebration Foods Are Never Fancy
Here is something worth thinking about: the foods most closely tied to festivals and community gatherings are almost never complicated. Nobody associates a school fete with a deconstructed risotto.
The foods that stick in our memories tend to share a few traits. They are simple. They are easy to eat while wandering around. They are visually fun. And they are strong enough in smell to cut through a noisy, crowded event.
Hot donuts, slushies, fairy floss, popcorn, a sausage sizzle. None of them will win a cooking competition, but all of them are memorable. The smell carries across the oval. The colours stand out. And the whole experience becomes part of the atmosphere itself, not just something you eat between rides.
The Sights and Smells That Have Defined Local Events for Generations
Some of the most recognisable foods at community events are also the ones you can watch being made. A popcorn machine rattling away beside a stall. A fairy floss spinner turning sugar into bright pink clouds. A slushie machine slowly churning through impossibly bright colours.
Across regional Australia, and certainly throughout Gippsland, these sights and smells have been part of local celebrations for as long as most people can remember. School fetes, agricultural shows, sports club fundraisers and community festivals all tend to share the same familiar atmosphere, and food plays a surprisingly large role in creating it.
For kids especially, the excitement often starts well before the first bite. Watching the food being made can be just as memorable as eating it. There is something almost hypnotic about a popcorn machine in action, and if you have ever watched a child stare at a fairy floss spinner, you already know that.
Why These Traditions Never Seem to Disappear
Food trends come and go constantly. Every few years there is a new obsession, whether it is smashed burgers, ube everything, or whatever the latest TikTok food trend happens to be.
But the foods tied to community celebrations rarely disappear. And that is because they represent something bigger than the food itself.
A day out with family. A local fundraiser where your kid’s school raises a few thousand dollars one sausage at a time. A country show where neighbours catch up after months apart. A festival where the kids run around the oval until their slushie-stained faces are barely recognisable.
Research from Frontiers in Psychology confirms that nostalgia is strongest when memories involve shared experiences with people who matter to us. Olfactory cues — smells — are more effective at triggering clear and emotional memories than visual cues like photographs. It is not about the food. It is about who you were with when you ate it.
And sometimes, all it takes is the smell of popcorn drifting through the air to bring all of that rushing back.
Because somewhere nearby, something fun is happening.
