Did you know Daniel Bernoulli ???

I wonder if Daniel Bernoulli also watered his plants . . .
A common principle in watering plants, and perhaps one of the basic I believe, is the application of Bernoulli’s principle:
• Water is only being absorbed through the root system.
• Absorption is induced by air movement.
• Stomata in the leaves is a hole that, somehow and so complex, extend all the way to the root system.
As air passes on the surfaces of the leaves, a suction effect (negative pressure as described in the Bernoulli’s principle) is created in the stomata resulting to an absorption effect in the root system.
A very good analogy to this is when you drink your cola using a straw.

Remember: water plants through the roots, not leaves.
