High School physics teacher for 35 years. Did workshops, assemblies, and classroom shows on a variety of subjects. I specialized in lasers and optics and included bubbles in those shows. Created a program called Build a Better Bubble using soap, water, and hydrated polymer as variables for students to truly experiment to find the best mix. I've been writing science text books for the past two and a half years and working on bubbles during the pandemic. Recently did my first bubble workshop again since things have opened up.
