OPPD issued a challenge to all 5th graders and we accepted. Using 20 strands of spaghetti, 1 yard of tape and string, build the tallest structure that could hold a marshmallow at the top.   Out of 8 teams we had 1 team actually complete the challenge and 1 team come close. It was much harder than we thought!  Congrats to Ben, Matt, and Rosa who built a structure 19 1/2 inches tall.
