Test Underwater Pressure 1. You need: a quart jar full of water and a drinking straw 2. What to do: Put the end of the straw just below the surface of the water in the jar and blow. Now put the end of the straw near the bottom of the jar and blow again. Which way is harder to blow bubbles? Water has weight, as anyone who has lifted a bucket
of water knows. The pressure in the ocean, or any body of water, is
proportionate to the depth below the surface. At the great depths of
underwater exploration the pressure may be tremendous and any underwater
vehicle, like a submarine, must be very strong in order to withstand
the weight of the water. |
