When Tracy Drier comes to Science Expeditions, the annual public open house held across the UW-Madison campus next weekend, he’ll arrive with a wealth of scientific glassblowing knowledge and, of course, his Wisconsin FireWagon.

The FireWagon is equipped with Drier’s tools of the trade: a delicate torch, a small cylinder of propane and a stock of borosilicate — glass that can tolerate heat and is chemically inert.
