(I'm duplicating my answer to your other question here.)
1) Fill a bowl with water.
2) Sprinkle small particles of something that floats into the water (e.g., talcum powder).
3) Put a bit of dishwashing liquid on your finger, and then dip your finger into the middle of the bowl. Watch what happens to the talcum powder.
This and some other experiments are listed at the website below.

Just blow a bubble - the reason bubbles are round is because the surface tension pulls equally in all directions. A sphere is the smallest something can be to have the lowest surface area to volume ratio.
