Check out NanoDays

For the sixth consecutive year at Highland Road Park Observatory, big things in the universe take a backseat to all things tiny.

Juana Moreno and her colleagues will celebrate nanotechnology from 2 p.m. to 6 p.m. Saturday at the observatory, 13800 Highland Road.

NanoDays will feature several hands-on activities for children of all ages. Visitors can see how big items are compared to nanoscale objects, understand how a scanning probe microscope allows scientists to explore the nanoworld, experience the effect of reducing the size of regular objects by trying to pour water out of a nano-cup, and learn about nanomaterials used in the manufacture of stain-free clothes.

Children and adults will also have a chance to build models of nanoscale structures, play with liquid crystals and make fluid magically part in the middle using magnets.

Additionally, the observatory will hold the March solar viewing session from 2:30 p.m. to 4:30 p.m.

Sponsors of NanoDays include LSU’s Department of Physics and Astronomy, LSU’s Center for Computation and Technology, LSU’s Department of Chemistry, the Society of Physics Students and the Louisiana Alliance for Simulation-Guided Materials Applications.
