Something special for first dance?

I'd start by checking with your venue to see what's allowed. The venue we used for daughter's Sweet 16 prohibited the smoke DJs often use -- it can make the floor slippery and it can trigger allergic reactions for people with issues like asthma....

As PP said, the smoke can get overwhelming especially in a poorly vented venue. The fog kind of lingers and makes everything sweat. Cups, glasses, floor anything that has a slippery surface. It is fun though!! What about a dramatic lighting effect?

Fog or smoke does make it slippery. A friend of mine did that and right after the dance someone had to mop the floor so that was kinda weird aha but it does make the aesthetic dreamy

Hmm... i might be the odd one out, but maybe get your guests to blow bubbles? bubbles make for the most beautiful photos at weddings. just an option! other than the smoke bombs (definitely make the air feel weird for a while) or bubbles, im unsure of what you could do. try to ask your venue about what is allowed/if they have any advice for something to make it all the more special. such cute ideas though! good luck

View Quoted Comment Yes that would be nice!

I would prefer the fireworks if they have it but if not the clouds would be fine!

We’re doing a snow machine. Our wedding is in January.

Fog does get slippery, and sparks can do melt spots in synthetic dresses, most of which are made of a petrolium based chemical polyester. And they burn easily. Have little moving colored spotlights, either bounced off the white drapery around the venue, or uplights to bounce of the ceiling. Go for an Aurora Borealis Effect, or simply criss crossing spotlights aimed at the dance floor from different angles, so you move in and out of them.
