Clouds of small bubbles stay in the air longer than confetti and look great in photographs. 

(This photo wasn't faked, by the way. The bubble floated past exactly at the right moment!)

Afterwards, monster bubbles entertain guests at the reception party while children play happily for hours, chasing bubbles and taking turns to make their own.

My bubble-liquid is itself an effective COVID-19 sanitiser due to its high detergent content. Bubbles will not be made by breath-blowing. Risk assessments are individually discussed with event organisers and I comply with all agreed precautions.
