Today, I was running low on toothpaste. To be able to get the last bit of it out, I had to apply pressure from the bottom of the tube. I was mindful that as I was applying pressure, it was being transmitted equally in all directions as it traveled through the fluid (toothpaste). This is related to what we discussed in class in Ch 3 of our book "Pressure and Fluid Statics": Pressure at any point on a fluid is the same in all directions.
