What can you build with 20 full pieces of spaghetti, one standard-sized marshmallow, a yard of masking tape and a yard of string?  The Omaha Public Power District challenges you to challenge your inner engineer and build the tallest structure you can!

Teams of three to four students currently in 5th grade are invited to participate.  Read more about the contest rules here.  OPPD is accepting electronic entries until 5 p.m., February 19.
