Homework Statement

a fun and engaging, visual way of showing laminar flow for young kids

Relevant Equations

no math can be used

I have been tasked by my fluid dynamics professor to create a 3 minute video showing and explaining laminar flow vs turbulant flow. It must be engaging and explain the concepts simply enough with no math.

I will be re-writting this definition below to suite the needs

""Laminar flow occurs when a fluid flows in parallel layers, with no disruption between the layers. At low velocities the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards. There are no cross currents perpendicular to the direction of flow, nor eddies or swirls of fluids. In laminar flow the motion of the particles of fluid is very orderly with all particles moving in straight lines parallel to the pipe walls.""

One idea i had was to have my fish pump pump some water at low velocity, and add some dye to it to see the smoothness of the flow and have a 3d printed boat in the water following the flow, then switch to the bubbler and the boat and see the difference in flow?? i could also show palying cards as part of the demo??

what other simple fun ideas to show laminar flow?

thanks

I like to use Google Images to get ideas for things like this. I did a Google Images search on Laminar Flow and got some interesting images. Maybe try adding other search terms into help you find more potential images that inspire some ideas for your video...
