White Water Rider
It promises to be a wet'n'wild race up (and down) the rapids as The X-tinguishers take on The Body Snatchers. The teams will have to build a boat, but not just any boat. Their boat will have to navigate a white water course. The first part is going up the river, which is flowing at 20 miles per hour, then coming back down ad re-crossing the start/finish line. Each team gets 3 tries and the team with the fastest time advances in the series.

The X-tinguishers are going to build a jet powered boat. The main piece they'll need is a jet pump, or impeller. An impeller is basically a propeller in a tube. Water is sucked in one end, spun round by the propeller and thrown out a smaller tube at the other end. The result is a jet of water that will push the boat through the water. They will have to be concerned with bouyancy and water resistance which will slow their boat down.

The Body Snatchers are going to build a platform of oil-barrels with an engine mounted fan that will blow them up the river. They will also have to be worried about fighting water resistance from their blunt ended platform, a high center of gravity, bouyancy...um...looks like they have to worry about everything.
