Creativity event this Sunday.?

Yeah, this Sunday morning i'm running an art table with a project that my creativity group just started on a few weeks agao. Problem being, i'm also including bubble painting to the art table, and for the project. I just wanna know, and this is for the girls only, if any ladies came to my art table and did some bubble painting, should I just watch them and focus on the bubbles rising or am I allowed to take the odd one or two videos on my mobile of the art in action as memories of the morning's event? I'd hate to have to watch the bubble painting in action each and every time a young lady has a go.
