Hello my raviolis. I just found this nifty little video of a bubble being broken in slow motion. Isn't it neat the way the bubble breaks from the entry of the stone and then sort of opens up all around to its end. When we see a bubble break it is instant and it looks like it explodes from the center.
I love to see how these things work and by slowing the process down you can see how it is done. Love to you all. Grandma-ma
