Can you solve the bridge riddle? - Alex Gendler

Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn’t so smart either. But now is not the time for regrets because you need to get away from these mutant zombies...fast. Can you use math to get you and your friends over the bridge before the zombies arrive? Alex Gendler shows how.

"The old professor takes 10 minutes and you have 17"
Guess who's the newest member of the zombie crew

Well you don't have to cut the bridge.. it'll collapse from the zombies.

[cherribomb]

I would probably spend the whole 17 minutes thinking how to cross the bridge 🤣

[Aussiesurti]

Step 1: tell the zombies one of them have green eyes. this will buy you enough time to cross the bridge regardless of what strategy you want to use as long as it's one hour.

Ted Ed: “You can’t swing across-“
Me: “Oh yes I can”

Plot twist: They all died while the Professor was doing the maths.

I'm so proud of myself for finally solving a TED-Ed riddle, and actually doing it on paper and thinking it out.

[randomzergling]

This riddle is unironically has scared me more than any horror movie. The visuals and music is just so unsettling. I couldn't turn corners in fear of the zombies when I was younger.

[inmyflopera]

As soon as I heard that the professor takes 10

SACRIFICES HAVE TO BE MADE
Lmao

[ngchorhong]

I find it absolutely HILARIOUS they had to remove befriend the zombies as an option just to shut the trolls up

[scoodybookypooonbreak]

"And you're still stuck on the wrong side of the bridge" So you run across in the dang dark.

[emmie]

My teacher did this riddle, and there were so many unique answers
Niamh: “Well they didn’t say you couldn’t sacrifice anyone…”
Millie: “use the boast as a raft”
Annie: “the professor stays on the other side with the lantern and knocks out the zombies with his cane, then walks across”
Beth: “cut open the lantern, start a fire, and burn the zombies to a crisp.”

[renzodelrosario]

Tell the zombies that at least one of them has green eyes

[degrelleholt]

I figured it out myself.  The problem was, it took me six minutes to figure it out!  So me and the lab assistant went across first, kept running, and made a pact never to speak of this event again.

[zynyie]

This is so nostalgic. I was a kid when I first watched it and I had nightmares but looking back, I’ve seen scarier lol. Thank you for a good riddle and my kid nightmare fuel.

[greenisgreenyeah]

why do the zombies actually look terrifying

[ThyStare]

And as you hand the lantern to the janitor and he and the professor vanish through the darkness crossing the bridge you hear the professor's voice shouting from a distant spot: "Did I say seventeen? sorry, I meant seven"

[blaster]

Why the fuck do I need a lamp to walk on a damn linear bridge.

[flameshard]

The zombies In this riddle used to terrify me as a kid lol

[bernardobertamini]

I'm sure a lot of people must have already commented so but the solution in the video is not the only one. It also works if the Lab Assistant (instead of the Internship student) comes back with the lantern (I'm referring to this part of the solution: 2:37 )
