| 4D40.10 | steric and oleic acid films | PIRA 1000 | |
| 4D40.10 | stearic and oleic acid films | A-53 | Films from drops of stearic or oleic acid are measured. |
| 4D40.12 | alcohol slick | M-221 | Place a drop of alcohol at the center of a petri dish containing a thin layer of water. |
| 4D40.13 | determination of drop size | Fi-15 | A ring proportional to drop size forms when dropped on filter paper. |
| 4D40.15 | Avogadro's number | TPT 2(2),81 | Use a BB's to model a drop spreading on the surface of water, then use oleic acid and do the real thing. |
| 4D40.15 | monomolecular layer | 16-5.10 | A "BB" model and the Oleic acid monomolecular layer. Pictures. |
| 4D40.20 | films | A-52 | Measure gold leaf thickness and show the black of a soap film. |
