The BELL JAR!!!
June 27th, 2008 by aeinspruchPossibly the coolest thing I saw in 8th grade science class was the air pumped from a bell jar and the marshmallow inside reacting to the oxygen free environment by crushing itself. I was mesmerized instantly by the imploding marshmallow. As I searched the internet for this week’s selection, I struck paydirt when I came across the Bell Jar website. Entitled “Vacuum Technique and Related Topics For the Amateur Investigator“, this site gives us the history of the bell jar, general information about them, and current suppliers of vacuum apparatus. I could play with one of these things for hours. SO if you have a natural scientific curiosity about Physical Sciences or you teach them, this is the site for you! Too cool………..
