Home Page --> Scientific Glassblowing Demonstrations
The content of these demonstrations is inherently scientific. The intent is to promote the sciences in general and scientific glassblowing in particular. When possible, try to coordinate the glassblowing with concurrent student projects. For example, an experiment in the chemistry lab may mean more to a student if he/she uses a test tube that he/she has made.
|Safety notes - Safety is always our first concern when working with glass, flames, and compressed gases. Set up your demonstration area in a manner to protect people and property. Use appropriate protective clothing and safety glasses, comply with all safety and fire regulations and guidelines and work with an assistant.|
Good demonstrations involve participation:
Note: To encourage student participation, I have added some peer-led leading to my most recent demonstrations. Selected students spend a half day at the glassblowing facility learning some basic glassblowing skills and learning more about the glassblowing shop. Those students then become the "instructors" to their classmates when we do the demonstration a day or so later. The student instructors do an admirable job of sharing information with the class, answering questions and encouraging participation.
Some suggestions and questions to ask during an effective demonstration include:
For the glass preparation you can have the students blow bulbs (using the same basic instruction as in Blowing Bubbles). 19 mm medium wall tubing works well. Try to make bulbs about 25-30mm as your objective and be sure they are not thin!
