Dawn Posted April 25, 2016 Share Posted April 25, 2016 (edited) I saw a collection of glass 'ornaments' in a window display that were on a heat lamp and using evaporation/condensation to push bubbles and liquid (i think an alcohol) around a closed system. I was wondering if this is a physics demo item that has a specific name? The ornaments looked to be blown glass with glass tubing all standing about 15cms tall. I'd be grateful if anyone knows the name or where I can purchase these from online? Thanks! Dawn Edited April 25, 2016 by Dawn Link to comment Share on other sites More sharing options...
