Real Life Air Pressure | Examples of Air Pressure in Everyday Life


Ted Beyer, Educational InnovationsSticking Your Nose Where It Doesn’t Belong!

by Ted Beyer

At Educational Innovations, our management staff meets often to coordinate all of the goings-on here. All sorts of topics come up, both business related and science related.

More than two years ago, our Director of Operations, Ken Byrne, shared a story with us relating to his brand new travel-style coffee mug, which he had gotten as a gift. I am sure you have run into these things many times – an insulated vessel with a liquid/air-tight cap. The cap, of course, has a hole along one edge for you to drink your beverage.

The story was one of many great examples of air pressure in everyday life.  It went like this –

He was trying to drink his coffee, but, every time he tried, nothing would come out. He kept thinking that he must be using his new mug incorrectly – perhaps he had missed an instruction or technique unique to this cup that was designed to help prevent spills or something. No, no, that could not be it — he could pour it out, easily enough, but whenever he brought it to his lips to drink – nothing…

The Chemistry of Silver Tarnish


Ted Beyer, Educational InnovationsEvery Dark Spoon has a Silver Lining – Using Chemistry on Silver Tarnish

by: Ted Beyer

The holidays have just passed, and for most people, part of the celebration involves getting out the “good” china and flatware to set a festive table. Like most people, I have a few pieces of silver and silver plate that don’t get a lot of use, but are nice to use on special occasions. Thing is, over time, silver tarnishes – it turns dark, and if allowed to continue long enough, it turns black. So out comes the polish and you get to spend all kinds of time polishing it. And with silver plated items, if you do that often enough, eventually, you will polish the silver completely off!

Spouting Off in the Classroom


Ted Beyer, Educational InnovationsThe Chinese Spouting Bowl

by Ted Beyer

When we are at one of the many educational shows we attend each year, teachers often ask what our favorite products are. I always point at two items – our eddy current materials (here’s that post!) and The Chinese Spouting Bowl. When I mention the bowl, invariably I hear – “yeah, I have seen that in the catalog – does it really work?” The simple answer is yes, yes it does. It not only works, it is amazing to see work, not that hard to make work, and most importantly, it can also be a powerful teaching tool. In fact, the Chinese Spouting Bowl is an ancient and fascinating object that can bring many different science scientific principals into the classroom in an unexpected way.Spouting Bowl

DIY Kaleidoscope


Norm Barstow, Educational Innovationsby: Norm Barstow

When I was an Elementary Science Coordinator, I used to visit the five schools in my district and each year introduced the Pringles® Kaleidoscope as part of the Sound and Light unit. At that time I used microscope slides, and it became quite a challenge to have the students line up and tape nine slides to make the triangular prism.  Fortunately, Educational Innovations began to carry Kaleidoscope Mirrors (SM-3), thus making the task much easier.

Here is all you will need to build a Pringles® can DIY kaleidoscope in your classroom.

Focus on Lenz’s Law

Ahhh, Eddy Current Tubes – you would never think that a hunk of copper pipe and a magnet could make anyone grin from ear to ear. I just love these things.

So simple in appearance, and yet so magical to see and use. Whenever I happen to have a set at home, I soon lose control of them to my wife who is just as fascinated by them as I am.

Although they can be used in fairly high end physics demonstrations, they are stunning enough that everyone who has a chance to see them is simply amazed.

Just realized – you may not have not seen one, have you? Here’s a video for you:

Kinda cool, huh? So, since I have (hopefully) gotten you to say “wow,” I’ll just bet you are wondering “why” — here’s some science:
