why do soap bubbles sometimes jump a couple of times before sticking to the surface of the still water?

Question

I was blowing bubbles into the bath. And like 1/3 would make a jump before sticking.

If this is relevant, the bubble liquid was 40ml water + 10ml dishwashing liquid + 1/3 teaspoon of sugar

Answer 1

bubbles are held together by surface tension, which pulls the water together. they want to stay round because that is the shape with the least surface area, everything is pulled in all the way.

when it lands on the water it can bounce because it squishes and the surface tension brings it back to being round so it jumps up a little. once it contacts the water enough to start mixing with the water it can save a bunch more surface area by blobbing down into a dome shape and it sticks.
