Spring Fest is over, but the images live on! Keep scrolling to see the EM images from this year's Spring Fest.
Spring Fest Review - 2025
Spring Fest is over and we had a blast hosting a booth for the first time! The PEMC put on a display of scanning electron microscope (SEM) images of pollen and bugs for the day and had a constant stream of visitors of all ages. We had so much fun, that we will certainly be back next year with more EM images of flora and fauna to delight and educate!
If you didn't find us this year, take a look at the images below to get a glimpse at what you missed. We hope to see you next year!
