the trajectory of water is used as indicator of pressure. The longer the trajectory, the greater is the pressure at that point of the liquid column. Water pressure at any point in a closed container is dependent on the height of the liquid above it.
a. With a hot nail, punch 4 identical small holes along a straight line on a large plastic bottle. b. Put a sticky tape on the holes to prevent water from leaking. fill the bottle with water. c. Now remove the sticky tape. Compare the trajectory of the water streams from the different holes. Why do you think water from the different holes have different trajectories? what does this indicate?
The water will exit the vessel's holes at different rates due to different pressures. The water exiting the top hole will exit slowest because it is under the least amount of pressure. The water exiting the bottom hole will come up the fastest because it is under the greatest amount of pressure.
The holes in sponges are called pores. These pores help sponges to filter water and capture food particles for nourishment.

I think they lay there eggs in water in little holes they make. Try watching Nemo LOL!

I think a Air molecule is same size as a Water molecule, But I'm not sure.
same thing the other guy said, a sponge
The area of Water End Swallow Holes is 113,000.0 square meters.
where does a giraffe get water
The 3 holes on the back of your boat serve different purposes. One is for draining water that may accumulate on the deck, another is for attaching a motor or other equipment, and the third is for allowing water to flow out of the boat if it gets inside.
