Underground science lab gives annual free festival

Talk about it

LEAD (AP) — The Sanford Underground Research Facility in South Dakota's Black Hills will host its fifth annual science festival next week to give the public a chance to hear talks by scientists and learn about research into cosmic rays.

The July 14 festival will feature talks by researchers studying dark matter, which has never been detected but is considered to be the most abundant form of matter in the universe.

Visitors also will be able to talk by video link with researchers 4,850 feet underground in the former gold mine in Lead. Other activities include hands-on experiments for people of all ages.
