| 2C50.00 | Vorticies | | |
| 2C50.10 | smoke ring | PIRA 200 | Tap smoke rings out of a coffee can through a 1" dia. hole. |
| 2C50.10 | smoke ring | 2C50.10 | Smoke rings are tapped out of a coffee can through a 1" dia. hole. |
| 2C50.10 | vortex rings | Fp-1 | Tap smoke rings out of a can with a rubber diaphragm on one end and a hole in the other. |
| 2C50.11 | smoke rings with LP gas | 17-8.6 | A rubber sheet at the back on a large wooden box is struck with a hammer to produce smoke rings capable of knocking over a plate. Fuming HCL and conc. ammonia produce the smoke. |
| 2C50.12 | vortex box | S-2i | A 15 inch square, 4 inch deep vortex box with a 4 inch diameter hole. |
| 2C50.15 | vortex cannon | PIRA 1000 | |
| 2C50.15 | vortex cannon | Disc 13-07 | Use a large barrel to generate a smoke ring. Blow out a candle with the vortex. Animation. |
| 2C50.20 | liquid vortices | PIRA 1000 | |
| 2C50.20 | liquid vortices | M-253 | A drop of inky water is allowed to form on a medicine dropper 1" above a beaker of water. This height is critical. The vortex will rebound if the beaker is less than 4" deep. |
| 2C50.21 | ring vortices on liquid | 17-8.4 | Bursts of colored water are expelled from a glass tube in a beaker of water. Also a drop of aniline sinks in a beaker of water. |
| 2C50.22 | semicircular vortex in water | 17-8.5 | A skill demonstration. Use a small paddle to form vortices in a small dish on the overhead projector. |
| 2C50.23 | detergent vortex | TPT 28(7),494 | A few drops of detergent in a jar of water are shaken and given a twist to form a vortex lasting several seconds. |
| 2C50.25 | whirlpool | 17-8.7 | Water is introduced tangentially into a cylinder with a hole in the bottom. |
| 2C50.30 | tornado tube | PIRA 1000 | |
| 2C50.30 | tornado tube | 2C50.30 | |
| 2C50.30 | tornado vortex | Fp-2 | A vortex forms in a large cylinder on a magnetic stirrer. |
| 2C50.30 | tornado tube | Disc 13-09 | Couple two soft drink bottles with the commercial tornado tube coupler and spin the top bottle so the water forms a vortex as it drains into the bottom bottle. |
| 2C50.35 | flame tornado | PIRA 1000 | |
| 2C50.35 | paraboloids and vortices | AJP 37(9),864 | A transparent cylinder is rotated at speeds up to 1000 RPM. |
| 2C50.40 | growing a large drop | Fo-1 | A vortex is formed in an air stream allowing one to form a large water drop. |
