After ten years of building wacky inventions, engineer Vin Marshall teams up with two of his oldest friends; mechanical engineer Paul Carson and inventor Eric Gocke, to build some of the zaniest engineering feats ever attempted. Tackling everything from robo subs to homemade rockets, the daring trio stop at nothing to break records, push boundaries and capture imaginations with their mind-bending inventions.

How many balloons could lift up a house just like in the Pixar film Up? Or how high could a rocket reach that's made only from material bought at a hardware store? Using a combination of hard science and innovative visuals How Hard Can It Be? is a fascinating three-part series that designs and performs these and other fun, jaw-dropping experiments.
