Strange Initiation

A young girl, Violet by name, was visiting with a group of her schoolmates at a friend's house. The air was filled with the noise of loud conversations, when an older woman called out for silence. She then asked one of the girls in attendance to remove something from a black bag she was holding. The older woman then announced, "Violet, you have the honor of being first!" Violet was then ushered to the center of the room where the older woman pushed a body part of an animal into Violet's hand. Suddenly, everything went dark for the young girl. Violet began to feel dizzy, and felt someone's hands on her. She then felt a slight push. As Violet staggered forward in the darkness, the loud chanting and shouting increased around her. Finally, Violet's hand bumped into something which, when the darkness was gone, gave her a feeling of pleasure and satisfaction. Was this scenario part of some bizarre, warped initiation into some strange cult, or is there a more pleasant explanation for these events.

The atmosphere seems ominous, but think about a common celebration where a group of young friends gather...

Violet was at a birthday party, and was selected to be first in the Pin the Tail on the Donkey game they were playing. She was successful in pinning the tail just where it belonged. The body part of the animal was, of course, the donkey’s tail.

Jim And Joey Were On Vacation And Driving Along A Deserted Country Road From The Town Of Kaysville

Jim and Joey were on vacation and driving along a deserted country road from the town of Kaysville to the town of Lynnville. They came to multiple forks in the road. The signpost had been knocked down and they were faced with choosing one of five different directions. Since they had left their map at the last gas station and there was no one around to ask, how could Jim and Joey find their way to Lynnville?

Think about what you can do at each fork in the road, and how you can use the process of elimination to your advantage.

They need to stand the signpost up so that the arm reading Kaysville points in the direction of Kaysville, the town they had just come from. With one arm pointing the correct way, the other arms will also point in the right direction.

The Money Has Been Stolen!

Right before a restaurant was about to open, someone stole all of the money from the cashier's desk. The chef said that he was working hard and didn't have time to walk or look around, so he didn't see anything. The security guard said that he was in the bathroom and didn't notice anything suspicious. The waiter said that he remembered seeing one visitor looking suspicious to him; somehow, he ignored the visitor and didn't stop him. The waiter got arrested for stealing the money. Why?

The hint is: Pay attention to the waiter's statement, specifically the phrase "somehow, he ignored the visitor..."

The phrase, "Right before a restaurant was about to open…" means that the restaurant was still closed. There couldn't have been any visitors inside. Therefore, the waiter is lying.

A Long Riddle - In A Far-off Kingdom, There Is A Castle With Five Rooms

In a far-off kingdom, there is a castle with five rooms. Each room has a door with a different color: blue, red, green, yellow, or purple. Inside each room, there is a person with a different nationality: American, British, Canadian, Dutch, and Estonian. Each person has a favorite animal, which is also different for each person: cat, dog, elephant, giraffe, and horse. Additionally, each person has a favorite food, which is different for each person: pizza, sushi, spaghetti, tacos, and waffles. Using the following clues, can you figure out who lives in each room, what their nationality is, what their favorite animal is, and what their favorite food is? The person in the blue room is not Dutch or Estonian. The British person's favorite animal is a horse. The person who likes sushi lives in the red room. The Canadian person likes pizza. The Dutch person lives in the green room. The person who likes tacos lives in the yellow room. The American person's favorite animal is a giraffe. The person who likes waffles lives in the purple room. The person who likes spaghetti is Estonian. The person who likes elephants lives in the room adjacent to the person who likes giraffes.

Here's a hint to get you started: Focus on the clues that mention specific room colors and nationalities first. Use the fact that the Dutch person lives in the green room and the person who likes sushi lives in the red room to start building your solution. Then, use the clues about favorite animals and foods to fill in the remaining rooms.

The blue room: American, favourite animal is a giraffe, favourite food is sushi. Red room: British, favourite animal is a horse, favourite food is tacos. The green room: Dutch, favourite animal is a cat, favourite food is spaghetti. Yellow room: Canadian, favourite animal is an elephant, favourite food is pizza. Purple room: Estonian, favourite animal is a dog, favourite food is waffles. Explanation: Clue #1 tells us that the person in the blue room cannot be Dutch or Estonian. This leaves us with American, British, Canadian, and Estonian. We can use other clues to narrow it down further. Clue #2 tells us that the British person's favourite animal is a horse, so they cannot be in the blue room. This leaves us with American, Canadian, and Estonian. Clue #3 tells us that the person who likes sushi lives in the red room, so the American person must be in the blue room. Clue #4 tells us that the Canadian person likes pizza, so they must be in the yellow room. Clue #5 tells us that the Dutch person lives in the green room, so they cannot be in the yellow room. This leaves us with British and Estonian. Clue #6 tells us that the person who likes tacos lives in the yellow room, so the British person must be in the red room. Clue #7 tells us that the American person's favourite animal is a giraffe, so they must be in the blue room. Clue #8 tells us that the person who likes waffles lives in the purple room, so the Estonian person must be in the purple room. Clue #9 tells us that the Estonian person likes spaghetti, so the Dutch person must like cats. Clue #10 tells us that the person who likes elephants lives in the room adjacent to the person who likes giraffes, so the Canadian person is just like an elephant. So the final solution is The blue room: American, favourite animal is a giraffe, favourite food is sushi. Red room: British, favourite animal is a horse, favourite food is tacos. The green room: Dutch, favourite animal is a cat, favourite food is spaghetti. Yellow room: Canadian, favourite animal is an elephant, favourite food is pizza. Purple room: Estonian, favourite animal is a dog, favourite food is waffles

The Bridge Riddle By Alex Gendler - TED-ed

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.

Think about the concept of "rate" and how it can be used to solve a problem involving time, distance, and speed.

At first it might seem like no matter what you do, you're just a minute or two short of time, but there is a way.  The key is to minimize the time wasted by the two slowest people by having them cross together.  And because you'll need to make a couple of return trips with the lantern, you'll want to have the fastest people available to do so.  So, you and the lab assistant quickly run across with the lantern, though you have to slow down a bit to match her pace.  After two minutes, both of you are across, and you, as the quickest, run back with the lantern.  Only three minutes have passed.  So far, so good.  Now comes the hard part.  The professor and the janitor take the lantern and cross together.  This takes them ten minutes since the janitor has to slow down for the old professor who keeps muttering that he probably shouldn't have given the zombies night vision.  By the time they're across, there are only four minutes left, and you're still stuck on the wrong side of the bridge.  But remember, the lab assistant has been waiting on the other side, and she's the second fastest of the group.  So she grabs the lantern from the professor and runs back across to you.  Now with only two minutes left, the two of you make the final crossing.  As you step on the far side of the gorge, you cut the ropes and collapse the bridge behind you, just in the nick of time.
