[Geysers] Strokkur and Geysir Video and Blue Bubble Questions

[Pat Snyder]

Thank you so much Alan and Eric. Your answers were very helpful. I will 
watch more carefully the next time I see Great Fountain erupt, maybe I 
will get lucky and see a blue bubble there.

And now I REALLY want to go to Iceland. A blue bubble that can rise to 
nearly eye level? With a water spike inside it? Incredible!!!
