We did the 2-hour glass blowing class at Through the Fire (three adults and a 10-year-old). The instructors are talented and patient. We all had a wonderful time, and all four of us had excellent take-home products. I made one of those hanging balls with marbled colors, and a clear paperweight with swirls of colors and bubbles inside. Really fun. The only caveat is that you need to return the next day to pick up items after annealing, so if you are just passing through that could be an issue.
