Olympic bobsledder Curt Tomasevicz will speak at 10:30 a.m. April 25 during the College of Engineering’s E-Week open house in Othmer Hall.

The open house, which culminates the 101st year of UNL’s E-Week, is 9 a.m. to 3 p.m. The event will feature engineering students demonstrating how engineers help the world. The presentations include:

• Civil engineering students’ redesign concepts for the intersection of 14th Street and Cornhusker Highway;

• Electrical engineering student teams’ unmanned aerial vehicles, room-mapping robot and a “fire-extinguisher car”; and

• Mechanical engineering students’ airplane de-icing system.

Other events include an “EGGineering” contest in which students design protective devices to protect eggs that will be dropped 50 feet from the roof of the Othmer Hall, and a high school bridge building competition. The bridge contest begins at 1 p.m.
