...fast frame rate would barely help. A bursting bubble happens so fast, I don't think 8FPS would cut it...
I agree that it won't guarantee that you get them while bursting, but several fast bursts I think will have a better chance of getting one of them bursting that single shot after single shot... and remember there are cameras like the 1D mIV that can do 10fps!
Also, another option would be to actually film them at 720p at 60fps with very fast shutter speeds, one could extract the burst out of a single frame of 1MP. It could work!
