Fun party trick: once you get the knack of making air currents with your hands, you can spin-stabilise and direct bubbles pretty much anywhere you want them to go without having to touch them. And smoke-filling them just requires a drag & exhale at the appropriate moment.
I once spent a very fun New Years Day in the bush, surrounded by a few thousand hippies, delivering metre-wide bubbles full of cannabis smoke throughout the crowd on request.
