Dry ice low fog: the first dance that looks like it is floating

What dry ice low fog actually is

Solid carbon dioxide, dry ice, is dropped into a tank of hot water inside a purpose-built low fog machine. The temperature difference forces it to sublimate rapidly, throwing off a dense white vapour colder and heavier than the surrounding air. Instead of rising the way stage haze does, it sinks and rolls outward at roughly ankle to knee height, the entire trick behind the name: the couple's feet disappear into a rolling white layer and they appear to stand on a cloud rather than a dance floor.

The consumable is the dry ice plus a steady supply of near-boiling water, both of which run down over the course of a song. As the water cools and the ice is spent, the fog thins, which is why the effect is timed to one song rather than left running continuously. A wedding wanting fog at 2 moments, the entrance and the first dance, needs either a second load timed between them or a second machine, not one unit running for an hour.

The licence position in South Australia

Dry ice low fog is not a firework and holds no explosive or pyrotechnic composition, so no South Australian pyrotechnician licence applies to it, in the same way none applies to cold spark. The question that actually decides whether a booking goes ahead is not the law. It is the venue's own written terms, because several Adelaide venues restrict fog and haze effects specifically as part of their fire-safety and cleaning conditions, independent of what the Explosives Act does or does not regulate.

Legal position stated as at 10 August 2026. South Australia's Explosives Act 1936 and the Explosives (Fireworks) Regulations 2016 are the operative law. The Explosives Act 2024 (SA) received assent on 19 September 2024 but had not commenced as at that date, and it will change licence names and fees when it does. Nothing here is legal advice: confirm your own position with SafeWork SA.

The venues that ban it by name, and the ones that do not

Dry ice sinking rather than rising is a genuine physical property, and the reason it is far less likely than haze to trigger a ceiling-mounted optical detector. That is a different question from whether a venue's written policy permits it, and 2 venues checked for this site answer that second question with a flat no.

Adelaide Town Hall bans candles and naked flame, smoke, dry ice, haze, confetti and glitter, naming dry ice specifically rather than folding it into a general smoke clause. Carrick Hill and The Pavilion goes further: its fire and special effects clause prohibits smoke and dry ice machines, candles, sparklers, gas cylinders and explosive devices, and recovers the MFS false alarm call-out fee from the hirer if the alarm is triggered. At both venues, dry ice is not available, and cold spark is the substitute neither policy names.

By contrast, the National Wine Centre of Australia bans confetti and rice and conditions sparkler exits, but says nothing about dry ice, smoke machines or CO2. Silence is not a yes, so the same effect still goes to the coordinator in writing before it is booked. See the venue guide and the venue directory for the full breakdown.
