Come see the world's largest and highest powered magnet lab during our FREE annual event that features fun for visitors of every age: hands-on demonstrations, self-guided tours of our fleet of world-record magnets, delicious food, and the chance to interact with our expert scientists. Get an up-close look at the world's strongest magnet - the 45 tesla hybrid - where there will be special demonstrations and performances throughout the day. This year’s theme - TIME - aligns with the MagLab’s 25th anniversary and celebrates science past, present and future. Special time-themed experiences only available this year include the ability to turn back time with a laminar flow demonstration, timed radar races, crystals as timekeepers, ancient geological samples, and some special Dr. Who-time lord demos. We’ll also have a travel through time scavenger hunt and a time vault where you can predict the future that will be opened at the MagLab's 50th Open House in 2045.
