Part two
This is the Dipsticks finished sub
The NERDS diver-tug
The Dipsticks sub looks good in action
They cleared a gate for 100 points but
lost 50 for brushing against it
Their final score, 150 points.
The NERDS look on. They seem worried.
One gate cleared! 100 points
But they used their feet which is a 
no-no. They lose 100 points
They got their points back.
Just 100 more to win!
And the NERDS win in spades with 300
of a possible 600 points.
