This is a really difficult question.

1. The Bamboo Ultralight Plane - Legend of Holy Rose
2. Flying Machine - Wasteland
3. Periscope from Rear view mirror and compact - The Gauntlet
4. Made bomb with camera flash - The Gauntlet
5. Defused bomb by vaporizing mercury with current - Hell Week

There were so many great ones, this list doesn't even do justice

EDIT: Nearly forgot the Explosive Nitroglycerin Paste in "For Love or Money"

The one where he took off his pants. Forget what it was and what it accomplished, but who cares?

To answer seriously, I'd say the tear gas hot water bottle from Blowout was too cool.

He does that again in Deadly Silents.

Making a canon from a muffler in Three For The Road is also one of my favourites.

when he made the jet pack thing outta a fan

You’ve all come up with so good ones! The way he used the map in “The Gauntlet” is absolutely fabulous. And it’s so cool how he could turn the situation and use the gas that was supposed to kill them in “The Ten Percent Solution” to instead save them.

I like the ones when he uses simple things, like someone’s earrings or his precious duct tape. Especially I like when Mac stops the bomb from going off with his ticket in “Phoenix Under Siege”. His situation gets so hilarious; should he take his ticket and follow his grandpa to watch the ice hockey game, but risk blowing up the building, or just leave the ticket there and miss the game?

"Every Time She Smiles", when and Penny stretched the clothes hangers into multiple figure eights and then lassoed the conveyer belt to escape from the holding room in the Bulgarian airport.

I like that MacGyverism to MacFan092985.

What always gets me about that particular MacGyverism is the force at which the chair breaks through the wall does not match the speed or force the moving conveyer belt would generate.

I guess you could argue that the pressure/force would have built up as the conveyer belt pulled harder and harder until the wall gave way.

Although I personally think the belt would have just stopped moving. Those belts only work on tension against the drive rollers I think so if something obstructs it the belt stops but the drive rollers can keep turning.

the one where Mac makes a hot air balloon out of materials laying around when trapped in East Germany in Gx-1.

This is the one that I always remember first, too. Although, I probably would have eaten all the chocolate before I reached the leaking acid tank.

LOL!

Welding with the quarters and the jumper cables

Sliding the map under the door and collecting the door lock key with it

I still love the Human Factors MaGyverisms. The newspaper and the lense to make a scope, using the dust & jacket for the hand scanner. The rope for crossing the floor to the entrance & the magnets in the paper, setting them alight and throwing them on the heat seaking drones. Marvellous!

I really liked how he used the flare pistol to escape the small submarine after being locked in it by the villains in "Deep Cover" (Season 5 Ep. 17). Also, another favorite of mine is in "The Gauntlet" (Season 1 Ep. 4) when he slides the map under the door and then pushes the key out on the opposite side, landing on the map. He then pulls the map out from under the door with the key on it. While nowhere near as dangerous as some of the other ideas, I always thought this one demonstrated how powerful an idea can be when thinking in such a way to solve a problem that may sometimes seem difficult.

Those are both great In fact, I just posted the one with the map as one of my favorites too.

Totally agree. Those are the types of MacGyverisms which I like too.

One of my all time favorite MacGyverisms is from Lost Love where MacGyver is testing the security system of the Ming Dragon. The security guy says "They can't avoid the lasers because they can't see them" to which MacGyver grabs a hand full of soap powder out of a nearby cleaning cart and throws it into the laser making the beam visible and responds "They can now." and proceeds to climb between the now visible laser beams.

For me that scene is iconic to the show. Dressed in bomber jacket and light tan trousers, taking a simple every day item and using it imaginatively to overcome a situation without even blinking an eye.

I see that Macgyverism the same way. Some of the ideas that didn't directly involve any villains or immediate danger are just as important to me as the ones that did because of the way they demonstrate Mac's way of thinking so clearly. Of course, RDA wearing the classic outfit always helps too

Same with me....I NEVER would have thought of this one!

It probably wasn't all that realistic, but I really liked the plane from the beginning of Legend of the Holy Rose.
