If you have ever wanted to blow bubbles in gak, create a nebula in a jar, or turn your smartphone into a digital microscope, head to Devonshire Mall on Saturday for a preview of Science Rendezvous.

Don’t worry if you don’t know what gak or a nebula is, trained presenters will be on hand to take science out of the lab and into the streets—or on this occasion, into the Chapters bookstore.

The preview event will run noon to 4 p.m. April 30.

The main event, featuring hands-on exhibits and demonstrations of scientific phenomena, is set for Saturday, May 7, in the Education Gym. Learn more on the Facebook page of Science Rendezvous Windsor.
