Chicken Crossing
A man has to get a fox, a chicken, and a sack of corn across a river. He has a rowboat, and it can only carry him and one other thing. If the fox and the chicken are left together, the fox will eat the chicken. If the chicken and the corn is left together, the chicken will eat the corn.

//How does the man do manage to cross the river?//

This one is my answer.]Bella Here is my answer Brilee

The man would first take the chicken across then he took the corn over to the other side .Then he takes back the chicken so it doesnt eat the corn.Then he takes the chicken to the other side but before the fox can eat the chicken he takes the fox to the other side then goes back for the chicke

the man mast get the chicken akros first then the man gos back and gets the seds akros then gos back to get the wolf. from tyran.

look guys the answer is simple if you have read the book treasuer fever well this is how it goes first the man takes the chiken across the river then he goes back to get the corn he brings it to the other side with he chicken but then befor the chicken eats the corn he takes the chiken back with the fox but then befor the fox eats the chicken he takes the fox to the side of the river with the corn so then he goes back and takes the chicken to the other side so then there all on the other side with out getting eaten

the dude should take the chicken over first because the fox wont eat the corn and the corn wont do anything to the fox so taking the chicken over first is right (lily)

//here is my answer Anthony//
 * Record your answer on your wiki page.** If you are unsure about how to do it or are getting stuck start a discussion on it using the title of the problem as the title for the discussion.

I think he would have to take the chikcen first then he would bring the seeds over and get the chiken and take him back over and get the fox fast and then bring the fox over and then go bake and get the chiken. (ryan).

Who Owns the Fish?
__According to the website where I found this puzzle it is attributed to Albert Einstein. He claimed that 98% of the world could not work it out. Can you?__

//There are five houses in a row and in five different colours. In each house lives a person from a different country. Each person drinks a certain drink, plays a certain sport, and keeps a certain pet. No two people drink the same drink, play the same sport, or keep the same pet.//

The Brit lives in a red house- The Swede keeps dogs The Dane drinks tea The green house is on the left of the white house- The green house owner drinks coffee- The person who plays polo rears birds The owner of the yellow house plays hockey- The man living in the house right in the centre drinks milk- The Norwegian lives in the first house- The man who plays baseball lives next to the man who keeps cats The man who keeps horses lives next to the one who plays hockey- The man who plays billiards drinks beer The German plays soccer The Norwegian lives next to the blue house- The man who plays baseball has a neighbour who drinks water.

I did it! YAY! : I checked it and it works! I was first!-(No peeking to copy the answer)Bella Mum and I Figured it out. and i might have deleted something up the top by acedent SORRY. Brilee Me and harvey worked it out!!!!!!GO ME!!Mackenzie:D I found it out i think well not for you to know how many times I had to restart anyway who knows where the hedgehogs live? here it is Anthony

I know were the hedgehogs live and i also know were the fish lives!!! from liam

I got it! Finally! With a teeny bit of help from Brilee. Here it is!

Band around the Earth


The circumference of the Earth is approximately 40,000 kilometres, and someone has just made a metal band that circles the Earth, touching the ground at all locations.

You come along at night, as a practical joke, and add just 10 metres to its length (one hundredth of one kilometer !)

It is now one four-millionth longer, and sits magically just above the ground at all locations

How far has it risen ... could a flea, a rabbit or even a man squeeze underneath it?


 * Record your ideas at the bottom of this page by editing it. Don't forget to add your name after your idea.

a flea because adding 1 four millonth does'nt make much of a difference. by christabel We worked it out and even rounded to FOUR decimal places it was still the same length with the band. So, if it was on the ground before, a inseey binseey baby flea MIGHT be able to squeeze underneath. Maybe. (What we did: 40,000 / 3.142 = whatever then the square root of that was thing. Then we did 40,000.001 / 3.142= whatever then the square root of THAT was thing2. Then the difference between thing and thing2 was about nothing, so it would be very hard to squeeze under) But if a person was ridicuously short, or a mini-person, (s)he might be able to go under! From Bella

The diameter of the world @ 40000.01kms circumference = 12727.275kms The diameter of the world @ 40000kms = 12727.272kms circumference the difference being .003kms on the dia. So the radius = .0015kms. .0015kms is .6666 of a milimetre this is approx the thickness of a light pen stroke. Not even a inseey binseey baby flea could fit under so there miss smarty pants !!!!!!!!!!!!!!!!! From Liam

The circumfrence of earth is 40000km if we add 10m to it it will be 40000,01km the formula for a circumfrence is circumfrence=pi(22/7)xdia.The symbol for pi is(π). U have (40000.01x7)/22=12727.275Km(dia) for (40000x7)/22=12727.272Km(dia) subtract the two from each other and you have 0.003Km.You have to devide by 2 to get an equal spacing 0.003/2=0.0015km, now there is 1000meters in 1 km so 1meter =0.001km. U have an answer of 0.0015Kmx1000=1.5meters. A really Short man a rabbit and flea will be able to walk under neath it. !!!!!! from tyran !!!**
