Mind Boggling Homeschool Science Experiment-ping pong ball will not float

Before we get lost in the science experiments at our exciting home, let me teach you some things that air pressure can do. The air around you have weights, and therefore it creates a force on your skin and on everything around you. This force is called air pressure. When the air pressure on the same object from all sides, the object is fixed, but as soon as the air pressure varies slightly, the object will move – making it seem magical.

The cool breeze you enjoy at the beach is due to the difference in air pressure. At the greater air pressure spreads, it can cause cyclone and cyclone. In the following the homeschool science experiments, I'll show you that the air pressure can do some things that are pretty magical and contrary to what you expect.


Flipped Glass water fool: fill a glass of drink with water until it is a full third. Now let's put an indexing card or a hardcover cover up. Next, turn the glass upside down while holding the cardboard in your left-hand position. If you now drop your hold on the hardcover piece, what will happen? The clear answer to the mind we are the cardboard will fall down and the water will spill all over the place.
Now drop your left hand out, while keeping your glasses upside down with your right hand. What's going on? Magic! The cardboard refuses to fall, keeping water in reverse glass – in contrast to what you think! How did this happen?
Let me reveal a secret! Keep in mind that the weight of air or air pressure at sea level is nearly 15 pounds per square inch (psi). Force 15 psi is pushing the cardboard up. Now the weight of water and air in the glass is pushing the cardboard down, but too weak for the atmospheric pressure of 15 psi. The hardcover piece cannot move upwards, and therefore stick to the glass margin. Sometimes you do not always have a mentor to help you practice your daily ping-pong, so the ping-pong machine is a great solution to help you get advanced in the sport. Refer to 5 best table tennis shooting machine use for practice for more information on the type, use and function of the ball machine.

Now we move on to a fun and homeschool science test and mind-boggling, right? 

Ping pong balls are not floats: and you just think you can be stubborn; Wait until you see the table balls in this experiment. Grab a hopper with a wide mouth geared upward and place a table ball in it. Your goal is to get under the hopper and blow up to make the balloon float. Start! What happened?

Try again! Are you disappointed not you? Table tennis will not float-contrary to what you think. How did that? 

Here's the answer: when you blow the air, it moves at a high speed. The air moves at high speeds just want to run fast and do not bother pushing objects into its way. Therefore there is low air pressure underneath the ping-pong table. The air pressure above the ball is – you've guessed it's correct 15 pounds per square inch. This air pressure pushes the ball back into the hopper.

If you are amazed at the gimmicks that air pressure can do, I have countless scientific tricks in the same house in my pocket. Therefore, your next step is to download a free copy of "tutorials on teaching the science of preschool teachers" that are filled in with great scientific experiments and activities.
