In episode 14 of season four, Mac’s somewhere in the Arctic Circle, on the hunt a missing 100 million in Russian gold. The gold is believed to be in a plane from WWII that’s crashed in the area. When an avalanche strikes as he and the others on board are buried underneath the snow and ice.
Of course, Mac was never worried about the situation, especially when he learned about all of the great stuff on the plane that he had to work with to get them out of there. There was a literal bucket of Russian vodka, along with an oxygen tank that he wrapped in a sleeping bag and stuck in the vodka like a giant Molotov cocktail.
Making a Hot Air Balloon
Hot air balloons work on literally that – hot air. The air inside of the balloon is heated to a point it’s much warmer than all that surrounds it. This causes the balloon to float like it’s a boat bobbing through the water.
When Mac finds himself trapped in the Alps, he didn’t panic. After all, it wasn’t the first time he’d been stranded at the top of a mountain with (seemingly) no way to escape before his imminent death at the hands of the bad guys. In this episode, he makes a hot air balloon out of scrap materials, in the middle of a gunfight. Of course, everything works out just fine and he’s able to evade the villains in his awesome DIY ride.
In an episode titled “The Road Not Taken,” MacGyver is called upon to come to the rescue of a few nuns and an orphanage full of children who are being hunted by maniacal soldiers in Asia. One of the nuns who’s in trouble just happens to be an ex-girlfriend of Macs.
Luckily, God was on their side, or so it seemed since Mac somehow managed to create a time-release catapult. The contraption was formed with rocks, branches, a bit of twine, and, get this: rosary beads. It’s no wonder it worked miracles!
The Booby-Trapped House
In the tenth episode of season one, Mac finds himself stuck in the house of a crazed British madman named Quayle who’s got the place rigged for death. The villain has all sorts of high-tech equipment, and he’s bent on ending MacGyver’s life. “MacGyver is the only blemish on my records, gentleman,” said Quayle.
Eventually, Mac is able to get away from the would-be killer by creating a heat-seeking gun decoy using a serving cart, rubber band, electric mixer, and part of a suit of armor. That was definitely one of the more memorable inventions on the show.
There but For The Grace
During this episode in season six, Mac goes undercover as a homeless man on the streets. He seeks answers and revenge after a priest friend of his is mugged and dies in the hospital afterward.
He befriends a mute named Danny, who he believes was a witness to the crime. Some have called this episode one of the slowest of the entire series, but it does have some okay scenes. Take for instance the toilet-bowl bomb Mac has to build to get himself out of that one.
