A chance to face the blast of a wind tunnel doesn’t arise every day, but the opportunity will be available Saturday on the campus of the University of Maryland.

Confronting the force of the Glenn L. Martin Wind Tunnel is among the events being offered during Maryland Day, an open house at the College Park campus. Others involve ice cream, cooking, gardening tips and what is billed as a 3D tour of the human brain.

More than 400 free events will be featured from 10 a.m. to 4 p.m. in what U-Md. President Wallace Loh called “a terrific opportunity for families to experience the joys of discovery.’’

Tours, demonstrations and exhibits will be available in areas that include agriculture and the arts. Sports fans will have a chance to meet coaches and members of the men’s and women’s basketball teams. Autographs from the football team will be available.

The university depicts itself as a center of innovation. In keeping with that theme, the school is inviting visitors to “explore our fearless world.”

Fearless? You’d better be. The university’s dairy will dish out an original concoction: “the Fearless ice cream,” billed as Tahitian vanilla ice cream studded with cacao nibs, swirled with caramel and accented with spicy Thai mango and red-hot pepper melba.

It was not immediately clear how much wind will be furnished in the wind tunnel, which is used for research development and education in low-speed aerodynamics.
