Purav, Michael and me(Jamie) Were building this all day and finally perfected it to get the bacteria, fish and the table. We have been stressing over it because of the importance of the mission combonation. The perfected attachment got us 58 points in 8 seconds! Our original design got us much less points and took so much longer. John's son Michael (who was on the sentinels last year) helped us get some brainstorming ideas.
