This First Friday, go “down the shore” with an evening of summer-themed science!

We’ll look at the powerful effects of UV light and the chemistry of sunscreen, chill out with the technology of portable coolers, and explore the science behind thermometers and barometers (crucial tools to help pick your perfect beach day). We’ll also take a fashion-forward journey through historical swimsuits and the synthetic fibers that keep us active! Enjoy hands-on crafts, see a pop-up from our library archives, and learn how to make the most of your next vacation.
