Bubble jump

and although scary, the kids couldnt stop themselves jumping right into the bubbles.... :)

couldnt help but performing a bit more of pubmedsearching, and found this paper in Science from 1969, where the author is describing the size and lifespan of his bubbles; so cool!!! here is a small citation:
"Bubbles, made from solutions A to F (Table 2), were beautifully colored, although rather thick at the beginning. After bubbles made from these solutions had lasted over 200 days, I became interested in blowing larger bubbles. Big bubbles were blown in a Plexiglas box (55.9-cm edge cube) (13), but they did not last more than a week. Then, Corning Glass Works provided first one and later three 72-liter Pyrex flasks (14), the largest spherical flasks produced in this country. They were perfect for my purposes, and many bubbles were blown to a diameter of 40 to 50 cm out of solutions A to F." (for the scientists: also interesting to see that the writing style of a paper is markedly different from nowadays, just from reading this small part its clear, no?)
