bubal Posted January 19, 2013 Share Posted January 19, 2013 This is how I made this Vacuum Bell Jar system for use in laboratory. You can use several sizes of bells (kitchen glass bowls) and you can input electricity through the 4 spark plugs. Link to comment Share on other sites More sharing options...
