ANIMAL LOCOMOTION T-SHIRT
Kids S - L / Adults S - XL
"Life in a Fluid": the relationship of the Reynolds number to animal locomotion.
The front shows how animals experience fluid at various Reynolds numbers and, based on this, the type of locomotion they use to move. It is interesting to note that a whale and an albatross behave the same way even though they propell themselves through fluids of different compositions (water vs. air).
The back carries the Iridescent educational non-profit motto.
