Dancing on the clouds" is a popular special effect used for first dances at weddings or other formal events. It involves the use of a special machine to create a low-lying fog that hovers just above the dance floor, giving the illusion that the couple is dancing on a cloud.

 

To create this effect, a dry ice machine or a fog machine is used to create the fog, which is then released onto the dance floor. The fog is chilled and heavier than air, causing it to stay close to the ground. As the couple dances, the fog creates a dreamy, romantic atmosphere that enhances the beauty of the moment.

 

The effect is often used in combination with lighting, such as color-changing LED lights or spotlights to create a visually stunning display. Overall, dancing on the clouds is a beautiful, memorable addition to any special event.
