The city has just opened its one-of-a-kind Faberge Egg Museum, with a single egg displayed on each floor of a 100-story building — and the world’s most notorious jewel thief already has her eyes on the prize. Can you help the thief formulate a plan that will drop the most expensive egg she can get safely into her waiting truck? Yossi Elran shows how.

I thought and, despite the given solution, still think that the correct approach to a problem is to divide the building into halves with each drop. So you start with the 50th floor, then, if it breaks -> 25th, if not -> 75th and so on.

This solution is obviously less precise, as if for example the egg cracks on first two throws you basically receive next to nothing information on which floor is suitable for the theft; but as it was said too many throws would be suspicious and the solution I wrote above requires twice as less throws to determine the correct floor.

The thief kinda looks like a compass for drawing circles

Why not binary Search???14 EGGS???… THAT'S TOO MANY!!!

I CAN DO IT WITH 7 EGGS

.

First Egg: try it on the 50th floor

If it doesn't break use the Second Egg on the 75th floor

If it doesn't break, use the Third Egg on the 88th floor

If it doesn't break use the Fourth Egg on the 94th floor

If it doesn't break use the Fifth Egg on the 97th floor

If it doesn't break use the Sixth Egg on the 99th floor

If it doesn't break use the Seventh Egg on the 100th floor

If the First Egg breaks on the 50th Floor, use the Second Egg on the 25th floor

ALWAYS GO UP / DOWN AT HALF OF WHAT WAS BEFORE

Half of 50 is 25 so I added 25 to 50, thus making 75

Half of 25 is 13 (12.5 rounded up), added to 75, thus making 88

Half of 12.5 is 6 (6.25 rounded down), added to 88 is 94

Half of 6.25 is 3 (3.125 rounded down), added to 94 is 97

Half of 3.125 is 2 (1.5625 rounded up), added to 97 is 99

Well… there's only 1 floor left to try… thus 100

So we'll need 7 egg replicas

==========================

OR… WE'LL JUST NEED ONE EGG REPLICA

At the 100th Floor, just swipe the original with the fake… and jump out the window while wearing a glider suit – parachute combo

==========================

Or possibly… just swipe the egg and jump out of the 100th floor wearing glider suit – parachute combo… NO REPLICA EGG NEEDED.

Solved it by myself <3

just get some pillows

Wait but she only has two replica eggs. I'm confused. Could someone explain?

Here's a great invention.

a n a i r p l a n eMy Questions-

a). Why couldn’t she just carry the egg when she was coming down the rope?

b). How do all the eggs cost more when they all are the same?

c). How did no one recognise her?

d). Why did no one question and check why a truck was there?

Don’t ask me why I have soooo many questions

(I’m a 5th grader that's why)

Call the police!

I got it right👁️👄👁️

This is an awful riddle that is exactly what I was thinking I just thought it would be kind of suspicious to drop 14 eggs from a high security building with insanely expensive knees

I thought you were to STOP the thief…

Or, ya know, just wing it.

Egg

I don't get how I still understand this

You can steal the egg by telling a guard that another girl is stealing,so just still the egg that is at the 100th floor and jump on a plane

Can't you use the elevator

Throws egg at 1st floorbreaksThrows thief at 100th floorbreaksWhy are we helping criminals exactly???

maybe take the 100th egg and take it to the truck?buy a parachute

Why Tedx is always wasting time in fantasy which is not even in anyway related to mankind

It's not very good if there's only ONE egg on each floor is it?

wait a sec

how can a egg be more valueable if it's the same look same weight

that doesnt make sense

because ISN'T WEIGHT GONNA TELL US HOW MUCH MONEY IT'LL COST.

so take the 1st 1 and go XD

when the video says it has a single egg displayed on 100 floorsMe:

diesAlso me before I died: damn that's a lot of floors

Can’t she use purple mattress to put in the truck when egg drop

DON’T STEAL IN THE FIRST PLACE

Solution say an egg is faulty on the phone . Disguise as an inspector and get the egg make 1 dollar counterfeit and replace do the same for every egg.

And if your savage blow up the museum when you have all eggs

If it's just an egg, I guess she can, I don't know, put it in her backpack or something so she climbs down with it? That way, she can carry multiple eggs with her from the 100th, the 99th, and so on floors

Always carry a backpack during a heist, kidsWhat would happen if the thief took the PERFECT REPLICA and replaced the egg she wanted to steal? She then takes her 'souvenir' back down the elevator, leaves in her getaway taxi, and no one ever knows.

You can do it with Max of 7 guesses. Cut it in half every time. 50,25,12,6,3,2,1. Start at 50 then Add or subtract depending on whether you need to go higher or lower. Works for 100, but idk about other numbers.

Take the gift shop egg and sell it for the same as the top floor egg if they really are identical

Drop the 100th floors egg from the first floor

And this is why I’m not a criminal

This is impossible for bean brain to do

Joke's on her, though, as there are only 57 surviving faberge eggs. That museum is stocking counterfeits
