Operation Junkyard - Season 1 Episode 2 Water Bailer

Sink or swim! The junketeers have to build an automatic bailing machine. Each team's boat will have the same amount and size of holes, plugged by rubber stops. At test time, the stops are pulled out and the boat starts filling up with water. Whose boat will stay afloat the longest? The most effective bailing machine, that keeps its boat floating the longest, wins.
