Called the Greatest Show (and Tell) on Earth, Maker Faires are part science fair and part county fair. Showcasing invention, creativity and resourcefulness, makers — tech enthusiasts, crafters, artists, educators, tinkerers, students and others — exhibit their work and share their knowledge and skills. Visitors to Maker Faire Milwaukee (MFMKE, for short) will find something different around every corner — makers, performers, presentations, workshops and much more.

Maker Faire Milwaukee  is a FREE event held at Wisconsin State Fair Park September 26 & 27.
