Well, probably it would have taken less time than your replies, anyway, I understand, the countdown has the precedence. Thereafter, there will be all the time to celebrate a bubbling 30th anniversary.
OK, I looked at it, and that one short segment looks like small bubbles first, which then turned into what may be foam, but of a thin consistency. Had the energy source abruptly cut off, whatever you want to call it would have quickly dissipated. Now back to watching that clock. I do not want to miss when it turns zero.
