 I think that's pretty cool, but then I selected
 the institution of higher learning I attended based
 on the integral role fire played in its campus life.
 
 Water

 Remarkably, not everyone enjoys the primal illusion of fire.
 
 Your task in this codelab is to transform the rising fire
-effect you see before you, into a beautiful, tranquil waterfall.
+effect you see before you into a beautiful, tranquil waterfall.
 This will require digging into some C++ code.
 
 Before you begin, you'll want to copy our fire program to a new name,
 since you might decide later that you like fire better, I know I do::
 
   cp fire.cc water.cc
   git add water.cc
   git commit -am "adding water"
 
 For this codelab, you'll only need to change `water.cc`.
 
 The task of turning fire into water involves two key challenges:
 
   * Alter the red-yellow palette of fire into a blue-green one.
   * Reverse upward rising flame into downward falling water.
   * Seed the waterfall from the top instead of the bottom.
 
 At this point you'll want to open up `water.cc` in the editor you
 picked earlier.
 
 I see a red door and I want it painted... blue
 ==============================================
 
 While PPAPI's 2D graphics API uses multi-component RGB pixels,
 our flame effect is actually monochrome. A single intensity
 value is used in the flame simulation. This is then converted
 to color based on a multi-color gradient.
 To alter the color-scheme, locate this palette, and exchange
-the red component (first) with blue (third).
+the red component (first) with the blue one (third).
 
 Hint: Focus your energies on the CreatePalette function.
 
 You can test you changes at any time with::
 
   make water
 
 What goes up...
