George is very impressed by the model papyrus boat that Steve has built for history class. Steve wants to find a way to test the boat out but when he is unable to in the museum he decides to go to Endless Park. But a stray current caused by a rainstorm sends the boat on its way down the river and down a storm drain. Steve and George try to find the boat at the local waste treatment plant but due to the recent storm, the boat has completely bypassed the plant and floated out into the ocean. There, the waste treatment facility uses a skimming boat to collect floatables-trash that people have dumped into the ocean. They decide that Steve’s boat may be floating in the ocean somewhere.
