In this video we learn how to check blood pressure. First, ensure that the patient is relaxed the cuff is empty of all air. The arm should be held at the level of the heart. The doctor will then start to pump air into the cuff to inflate it. The doctor will do this until the pulse is not felt anymore. The pressure of the cuff will start to raise, then they will slowly reduce the air from the cuff. The doctor will listen to the flow of blood through the artery as the air is leaving the cuff. N...
This video shows you how to perform tire maintenance on your vehicle. In order to check the tread wear on your tires, you will need a penny. You will have to check the entire tire for wear, because tires may wear away unequally. Just slip the penny between the tread. If you are still able to see Lincoln’s entire head, then you will need to replace your tire(s).
In this video Dr. Carlson does several experiments to illustrate how a vacuum works. A vacuum is created when all the air is removed from an object.
Tire pressure is often overlooked, but can decrease your fuel mileage if you tires are not properly inflated. Have you ever peddled a bike with low tires. If you have, then you know it was much harder than when the tires are aired up. A car is no different. Low tires requires the engine to work much harder as well.

The pressure underwater is undeniably strong. If you were to fill a balloon with water and take it underwater, it would not burst but would stay the same size because liquids are not compressed. The pressure is the same, inside and outside of the balloon. If you were to fill that same balloon with air instead, the lower it dives into water, the more it shrinks, until it eventually can't take the pressure anymore and bursts.
This video shows you how to bleed a towel radiator like a professional. The radiator is hot at the bottom and cold at the top, which means that there is air in the system and the system will have to be bled. To bleed the system, you will have to open the bleeder valve with a key or flat screwdriver. Turn off the system first, so that no more air can be drawn into it. Open the bleeder valve slowly by turning with the key or screwdriver until you hear air and then stop. If the air stops quickly...

This video shows how to use a tire gauge. The first thing that you do is remove the valve cap off of the tire. Use the open end of the tire gauge. Put is onto the end of the valve. Don't use the other end of the gauge. The part of the gauge with the little round center piece in it is used to let air out of the tire. Once you have put the gauge on, push it firmly onto the valve. The air pressure in the tire will push the gauge measuring device out of the end of the tire gauge. You can look at ...
This video shows you how to break a yardstick with atmospheric pressure. The instructor first lays a ruler halfway on and off of a table. He then covers half the ruler with newspaper. The instructor states that you can chop the ruler in half with your hand because the air holding down the paper will keep the ruler in place. The experiment does work correctly and he did break it in half perfectly. This instructor seems to have many similar videos on the subject.
A classroom demonstration of the effects of lowering the air pressure on the boiling point of water.
Using a huge jar and with water colored with die in it you can make clouds. To do this set up the apparatus as shown in the video. Now open up the top valve and blow air into the jar. Now this causes the air inside to be compressed as we are pushing more air into the confined jar. This creates a high pressure inside the ball. To understand how clouds are formed you need to know two concepts. The first concept is that as pressurized gas expands it cools. The second thing is that warm gases can...

The video featured in this article demonstrates the function and design of a powerful form of air cannon that operates using a purpose made valve that opens very rapidly. This allows for a massive amount of pressurized air to be released at once to throw a projectile many hundreds of yards. The design of the cannon also allows the barrel and the air chamber to occupy the same space, and so it is very compact and manageable which makes for an enjoyable shooting experience.
