comment How come squeezing a water bottle makes the water come out?
"material collapses where I squeeze it, but expands in other areas, resulting in a constant volume" sounds to me like "I bet 100\$ on horses, and got 5\$ back at the cage, resulting in a constant wallet volume"

comment Explaining to a five year old - why don't bubbles run like water
There is an error this answer: the surface tension of the water/soap mixture is not 'very high'. This implies that it is higher than water. However, it is lower than water. Try putting a piece of paper on water that drifts, and then add soap: it will drop. See exploratorium.edu/ronh/bubbles/soap.html. This page incidentally would be very interesting the questioner's 5 year old! Has she ever wondered... why is it so hard to get bubbles from plain water?
