Watch the Re-Inventors test a torpedo designed 500 years before the first self-propelled missile was even conceived.
This invention was designed to run on waterpower instead of muscle, but testing it will take all of their strength.
See what happens when the Re-Inventors attempt to get an ancient troop transport wagon into fighting shape.
By the 1930s, more cars hit the road... and more pedestrians got hit by them. Our hosts put one old solution to the test.
Our hosts test how this Soviet winter troop transport vehicle would survive against Russian weather and artillery fire.
Is this 1940s iceboat winter-ready or skating on thin ice? The Re-Inventors bundle up to find out.
It looks like a doghouse resting on a wet suit, but this 1916 invention could have saved countless lives lost at sea.
A steel helmet with an air-power-triggered gun welded to the top. What could possibly go wrong?
As man approached the 20th Century, the race for the skies captivated the imagination of inventors everywhere and all kinds of bizarre flying machines were conjured up. Included in the mix was a pedal-powered ancestor to the helicopter, patented a decade before the Wright Brothers first conquered the skies. By all indications, it was never built or tested, but if this anonymously designed machine can actually lift off, it would be a history-making moment. Join Re-Inventors Matt and Jeremy as they take this chopper on a test flight.
See if a little wishful thinking and a lot of hard pedaling can get a 19th Century flying invention off the ground.
Can Matt and Jeremy get this bizarre one-wheeled bike in gear, or will they need to put the brakes on the whole thing?
