Top Five Physics Experiments Using a High Vacuum Pump

As a member of the science education industry, often teachers ask what is the best and most vivid experiments they can do in their classrooms to teach physics with a high vacuum pump. Over the past ten years, these five have become my favorite physics demonstrations demonstrating properties of matter and high vacuum physics.

Of course, to get started, you’ll need a vacuum pump, high vacuum tubing with tubing clamps, a vacuum pump plate, and a good quality bell jar. It also doesn’t hurt to have some vacuum grease or petroleum jelly handy to lubricate and seal between the bell jar and the pump plate. And now onto the top five:

5. Shaving Cream Expansion – Put a little dab (technical term) of shaving cream inside your bell jar (which is then sealed onto the pump plate), turn the pump on and watch the molecules spread themselves out and the Shaving Cream grows! Be careful not to let it run too much where you pull the Creme into the vacuum pump though!

4. Grow a Balloon – place a balloon, filled a little bit and tied off inside your bell jar and turn the pump on. Students will be curious as to why the balloon expanded while the air is pulled from the chamber.

3. Springtime (Easter) Peep Monster – place one of those terribly unhealthy, yet tasty, sugar coated marshmallows, THE PEEP, inside your bell jar. Turn on the pump and watch your baby peep turn into a Stay Puft Marshmallow Man peep!

2. Did you hear a bell ringing? – place an electric bell or kitchen timer inside your chamber and turn on the pump. Make sure the bell is turned on! As the air molecules are pulled from the chamber, the sound will slowly disappear until it is gone! Great way to explain to students why an astronaut would never be heard if he were to start screaming while in outer space.

1. Cool Boiling Water – My all time favorite. It is absolutely critical that your pump is a “high vacuum” pump and not just a vacuum pump. You’ll need to pull a much higher vacuum than the 25″ of mercury some pumps offer to do this. Place a plastic bottle or petri dish in the chamber filled about half way up with water. Demonstrate to your students that the water is at room temperature and not hot to the touch. Put it in the vacuum chamber, turn on the pump, and in no time you’ll have room temperature water simmering at a rapid boil. What better way to explain the effects on vapor points in different atmospheric pressure?

You can do a quick search on the internet and find all of these supplies from virtually every science education dealer. One tip, keep an eye on your vacuum pump oil level and drain and change any contaminated oil. Be sure to use “High Vacuum Pump Oil” as standard vacuum oil or other “home remedy” solutions (See: motor oil, vegetable oil, etc) will not allow the pump to continue operating properly!

Feng Shui and Quantum Physics

Both feng shui and quantum physics are intricately connected, down at the subatomic level. It is the blend of the conscious intention and observation of the macrocosm and microcosm interaction, the ebb and flow of wave and particle in a cosmic dance around and through us. The millennia of years of observation by philosophers and monks, and the attempt to have some control over the surroundings, has brought us this study, which can be called the law of the flow of life energy.

Quantum physics comes in to explain how something as ethereal as energy flowing through our daily lives could possibly be controlled. Those who study the field of geomancy, dowsers, architects and interior designers, psychics and healers, can all attest to how important the flow of life energy is. The good ones know it instinctively and the denser, less sensitive ones can learn through practice. We see this throughout our days with such people; you know the kind: they walk into a home, tweak the placement of a few things, and suddenly the uninviting becomes a model home. What they are doing is feeling the flow of energy through the home-the blockages, the too-rushed, the stagnation-and moving items to allow the energy (chi) to waltz into each part of the home, energizing and freshening as it goes.

All life organisms can feel what is good for them and what is dangerous. They might not pay enough attention to those feelings but they do have them. When entering a home for the first time and observing the animals in the home, it’s pretty obvious how the chi flows. If the animals and humans are relaxed and happy, the chi is flowing well; if nervous or agitated, the chi is somehow incorrect. With feng shui ‘cures’, even the worst situation can be somewhat remedied-although the remedy might have to go farther, such as calling in a Buddhist monk to deal with evil energies.

For most people, applying the feng shui cures is relatively easy. Get a beginning book on feng shui, assess the flow of chi and what is desired, rearrange furniture and change colors, and apply the cures to what cannot be changed. For bad chi situations, there are such things as the 5-element pagoda, 7-metals ringing bell, wind chimes, lights, faceted crystals, protective guardians, and yang water features. To attract good chi, there are money toads, lights, crystals, yang water features, wealth pots, wu lou, and various deities in statues and photos. What works varies with the problem and the desires. The whole idea is to decrease the inauspicious energies and increase the auspicious ones. One of the best ways to do both is the Flying Star school of feng shui, which addresses the movements of such energies throughout cycles of time. It’s easy to be peaceful when life flows gently and feng shui can help that to happen.

Spiritual Quantum Physics and Your Higher Self


I use the word ‘higher self’ to mean the highest aspect of man. You may call it your soul, your spirit, your conscience, it does not matter.

It is the highest level of consciousness (being) that man can attain in any one incarnation. It is at this point that man can do the most good for himself and others.

According to the Laws of Spiritual Quantum Physics we constantly ‘blink in and out’ of the Quantum Ocean, Mind of God for one purpose and one purpose only.

To continually raise our levels of consciousness. This way we advance closer and closer to our ‘higher self’ our soul.

Attaining this Goal will allow our ‘higher self’ to work with us 24/7 in all our earthly dealings.

But in order to get in touch with our ‘higher self’ it is necessary for us to destroy all our negative emotions. Negative emotions shut down the door to our ‘higher self.’

If we only knew what we lost by continually enjoying our negative emotions and allowing them to run our lives we would be horrified.

Since we cannot kill off our emotional nature all together we must learn to purify our emotions.

The purification of our emotions starts with the observation of and the separation from these negative emotions. Hate, lust, greed, fear, anger are a few of them.

In the great work of our lives to become more conscious and in touch with our ‘higher self’ observation and separation from our negative emotions must become a daily work for us.

There are those who say if there is a God why doesn’t he help us nor do it for us. Why doesn’t he change us into the marvelous negative free beings we were supposed to be?

Because we were created self-developing organisms capable of becoming God’s ourselves. But we must EARN this state of being by ourselves.

If God or anyone else could transform us into a wonderful state of higher consciousness, negative free being the whole meaning of life on the planet Earth would have to be altered.

We blinked out of the Quantum Ocean, Mind of God, as self-developing organisms, as potential gods for the sole purpose of doing it ourselves. No outside help is needed. No second coming or intervention of ‘higher forces’. No 7th cavalry. We do it all alone or we don’t do it at all.

It is man’s level of consciousness (being) being both individually and collectively that attracts the quality of life on this planet.

Wars, cruelty, horror, greed, immorality occur (look at TV and the newspapers) because man’s collective level of consciousness (being) on the planet today is at a very dangerously low level.

There is no guarantee that we will not be swept away the way Atlantis and other civilizations before that were.
