To pass the time you scoop river water into your mouth and see how far you can spit it out. S . . . sp . . . pout-mouth!!! The results aren't all that impressive.
  1. Try to bounce your water spray off of nearby stuff like the inner tube, the cave wall . . . uh, passing fish.
  2. Take the opportunity to finally whip out your crocodile soap and use your face fountain to take a spit shower.
  3. Hold as much water as you can in your mouth and do funny voices.
