Pounds Of Sugar Riddle
The grocer had ten customers, each wanting to buy a 2 pound bag of sugar. A 20 pound bag of sugar had been delivered that morning, but he had not yet divided it because he could only find the 5lb and 9lb weights. One of the customers, getting impatient, showed him the quickest way to measure the sugar with the two weights he already had. How did he do it?
Hint:
Weigh out 4 pounds of sugar with the 5lb and the 9lb weights in different pans of the scales. With the 4lb weight , weigh three more lots of 4 pounds each - the remaining sugar will also weigh 4 pounds. Divide each 4 pound portion equally on the two sides of the scales.

The Detective Trap Riddle
Detective Sara Dunts was called in for an investigation on a Saturday morning. Mr. John Gooding had mysteriously vanished from his one story home, Sara was told. "I'll phone Mrs. Glen, the caretaker, and get you the address." Detective Chad Sandlers, Sara's partner, said. Sara stood waiting as he made the call. "Okay, everything's set. Mrs. Glen will be expecting you in half an hour at 232 Parker At." Detective Chad said.
Sara hopped out of her car and walked up the long path that led to the house. Right away she was ushered inside by Mrs. Glen. "Detective, I'm so glad you came. The last place I saw Mr. Gooding was in his room. I suspected that would be your first question." Mrs. Glen said somewhat nervously. She walked Sara into the other room. "Up here," Mrs. Glen called from a twisting flight of stairs. The front door banged shut just as Sara started up the steps. "Oh, I must have left the door open. The wind must have shut it." Mrs. Glen said. Again they started up the stairs.
They walked up the enormous stairway. Halfway up detective Sara noticed a weather vane through the window. She realized that the wind was blowing west and in order for it to have shut the door it would have to have been blowing east. Then Sara realized for the first time that there was a third set of footsteps on the stairs. Then it dawned on her and she realized she had walked into a trap. How did Sara know she had walked into a trap?

How did Sara know she had walked into a trap?
Hint:
Detective Sara Dunts realized she had walked into a trap when she heard the extra set of footsteps. Hearing the footsteps on the stairs made her remember what her partner had said, "Mr. John Gooding had mysteriously vanished from his one story home." She then realized that this was not Mr. Goodings home because at that very moment she realized that she was climbing stairs in a supposedly one story house. Sara immediately called for backup and arrested Mrs. Glen. She then walked down the stairs to find Mr. Gooding near the bottom. The two had planned on kidnapping and killing Sara for putting Mr. Goodings niece and Mrs. Glens son in jail for murder. Both went to jail to serve their time. Did you answer this riddle correctly?

A Walk In The Desert Riddle
Four men walk into the desert. Suddenly all four are simultaneously knocked out. They awake buried to their heads in the sand unable to look anywhere but straight ahead. They are positioned so that each man sees another's head before him. However between the first and second man there is a separating wall.
So the first man sees only desert. The second man sees only wall. The third man sees another's head and a wall. The fourth man sees two heads and a wall. On top of each mans head is a hat. The underside of each cap is black, but the outside of each cap is either blue or white. Before any of the men can speak, their captors tell them if they speak, they die. However, if any of them can guess the color of their cap on the first try they go free. The captors tell them that there are two blue caps and two white caps.
Being an omniscient observer of the situation, we know that the order of the caps are: blue, white, blue, white. So knowing the perspective of each man in the sand, and that they can only see the color of caps/wall/desert in front of them, which of the four men knows for certain the color of his own cap. More importantly: why?

So knowing the perspective of each man in the sand, and that they can only see the color of caps/wall/desert in front of them, which of the four men knows for certain the color of his own cap. More importantly: why?
Hint:
The third man. This is because he knows there are only two of each color cap. If the man behind him (the fourth man) saw two caps that were the same color in front of him, he would know that his own must be the opposite. However, because the caps alternate in color. The fourth man has only a 50% chance of getting his hat color correct, so therefore he stays quiet. The third man realizes that the fourth man is quiet because he must not see two caps of the same color in front of him, otherwise the fourth man would say the opposite of the caps in front of him. Therefore, the third man presumes his own cap must be the opposite of the mans in front of him, and his presumption is correct. Under this same logic, after the third man speaks his color hat, the second man, even though he sees only wall, would be the next to go free, because he knows his cap must be the opposite of whichever color the third mans cap was.

Swinging At The Park Riddle
Which swings faster? And more importantly, why?
Hint:
The speed at which a pendulum swings is called the period and given by the equation:
2 x pi x square root of (length of rope from fulcrum to Center of Mass divided by gravity)
Since gravity is constant, the only thing that effects the period is the length of rope. In the above scenario, you assume the man is taller then the child. Therefore his center of mass is higher. This makes the distance between the fulcrum to the center of mass shorter then for the child. The man swings faster. Did you answer this riddle correctly?

Week Long Vacation Riddle
Hint:
The Graveyard Of Ol' Man Jenkins
There was a girl who was extremely brave and always bragged about how brave she was. Many of her classmates got sick and tired of her boasting, so they decided to play a trick on her. One day, a group of boys and girls walked up to her and said, " If you're so brave, we all dare you to go to the old graveyard at the back of Ol' Man Jenkins mansion all alone at midnight. Stand in front of a tombstone, rumor has it that if you do, a bony hand will reach out and grab you, dragging you underground! You said you were brave so that shouldn't be so hard! To prove that you actually went, stick a knife in front of a tombstone so in the morning, we'll know you were there." Of course, the girl couldn't refuse and agreed to the dare. At midnight, she did just as her classmates asked and went to the graveyard with a pocketknife. The night was cold and windy, blowing her dress, chills went up her spine. She slowly walked up to a tombstone and quickly stuck the pocket knife into the ground. She was beginning to feel not as brave as she thought she was. Turning around as fast as she could, she just wanted to get out of there right away! But, there was a problem. Something was stopping her from moving. Was it a bony hand trying to drag her down? A shrill scream was heard. The next morning, the boys and girls went to the graveyard to see if the girl had been there. To their horror, she was there, dead.
1) What prevented the girl from escaping the graveyard?
2) How did the girl die?
1) What prevented the girl from escaping the graveyard?
2) How did the girl die?
Hint:
1) The girl was wearing a dress at the graveyard. It was dark, so she hadn't noticed where she stuck the knife in the ground. She accidently stuck it in her dress (and the girl DID NOT get hurt by the knife in any way). That is what prevented her from running away.
2) Since the knife had her stuck, she was frighted that the rumor of the bony hand was true and had grabbed her, trying to pull her into the ground. She was truly terrified and died of fright. Did you answer this riddle correctly?
YES NO
