When two soap bubbles of different sizes are connected by a tube and isolated from outside air, they will equalize in size because the smaller bubble has higher internal pressure due to stronger surface tension forces, causing air to flow from the smaller to the larger bubble until equilibrium is reached.

What happens when two bubbles of different sizes are connected?Added:
All wish to know, but few the price will pay.
This is the disease in the world.
The double bubble, remember? Oh, this is a beauty. We had a T tube a T tube with two funnels so and a tube here which permitted me to blow some air into and then I blew up two bubbles. I blew a small bubble and I blew a big bubble.
And then I shut off the connection with the outside air so that the bubbles are connected with each other, but not with the outside air. Question, what now ensues? What do the bubbles do? What happens?
>> my answer was that they equalize.
>> Right. Everybody says they equalize.
