What Could Possibly Go Wrong?

Trash Can Rocketeers

42min - The physics of flight are tested when the ultimate trashcan rocket is constructed. A solar powdered death ray is built using TV parts, the sun and a little ingenuity. Also, the guys try to execute the perfect powerslide.

In-Human Slingshot

42min - Kevin and Grant create a fast motorized trike and turn a childhood game into a risky test of distance and accuracy with their uber water slide. The rapid-fire action of a meatball Gatling gun takes culinary arts to a new level.

Lawnmower Jousting Royale

42min - Grant and Kevin challenge each other to lawnmower jousting for backyard glory. Competition is fierce in the inaugural mini-weapon challenge, and the guys attempt to build a water, shock and bullet resistant cell phone case.

Homemade Hovercraft Hijinks

42min - Kevin and Grant test their skills and build a homemade hovercraft capable of crossing land and sea. Next, they make a merry-go-round produce Top Gun g-forces and use magnetic boots to attempt to defy gravity.

Concrete Canoe Challenge

Jumbo Paper Plane

42min - Grant and Kevin create a giant paper airplane that can fly over 200 yards. They try to stop a moving car with no brakes using their James Bond car brake, and they use pneumatics to create the ultimate beer delivery.

Deadly Donuts of Fire

42min - Kevin and Grant turn a blast of air into a ring of fire when they build a vortex cannon. They use magnets, superconductors and quantum physics to send a levitating racer around a track and make a frosty bulletproof glass mug.
