So you think you can dance?  Are you smarter than a 5th grader?  Well here's a challenge for you.  Solve this "simple" riddle and see if your smarter than the average person.

Petrie

You have a scientific petrie dish in which you exposed a primitive organism that was discovered in the ice caps of Mars.  As you watched these organisms, you found that they divided themselves every minute in two equal parts that are of the same size as the original organism.  Which would in turn divide the next minute and so forth.  The petrie dish in which you started observing the process was full at 12:00 am in the morning at 7 degrees celcius.  When was it half full?  (You have 10 seconds to come up with the answer) 9...8...7...6...5...4...3...

A wise man asked his student, "When the day after tommorrow is yesterday, then today will be as far from Sunday as that day was which was today, when the day before yesterday was tommorrow."

What day was the wise man talking about?

Monkey

Since you guys are sooooooo smart.  I have another quick one for you to answer.  This time, I'll give you the answer within a  couple minutes on my next post.

There is a very, very tall coconut tree, and there are three animals.

King Kong, Gorilla, Orangutan, and a Chimpanzee pass by.

They have a competition to see who is the fastest to get the bananas. 

Who do you think will win?

Your answer will reflect your personality.  Try and answer within 30 seconds.

Got it?  See my next post.

Here's your  2 questions (since they're easy) for the weekend...

1.  How can you throw a ball as hard as you can and have it come back to you, even if it doesn't hit anything, there's nothing attached to it, and no one else catches or throws it????

2.  A girl who was just learning how to drive went down a one-way street in the wrong direction (let me clarify...)by herself, but didn't break the law.  How is that possible???

These should be easy ones... I'll give you the answer on Monday if you really can't figure these out.

Bulb

OK OK you waited for the answer to my little brain teaser long enuff.  Here it is...your gonna love it...your gonna kick yourself...your gonna say that it was too simple to figure out....your gonna realize why I said all laws of physics are present...OK....read on...

SOLUTION:

1st, you should flip on one switch and wait for 10 minutes.  That bulb is going to heat up and get really hot.  Figured it out yet?

2nd, before you enter the room with the bulbs, turn off your frist switch that you had on all this time and turn on the second switch.

Now when you enter the room, look at the two lights that aren't on.  Feel for the bulb which is still warm and that is your first switch.  Your second is the light that is currently on.  Your third switch that you haven't switched on yet is the other bulb that is off and is cool to the touch.

Got it?  Hate that answer?  Kicking yourself for not figuring ot out?  Don't worry you can redeem your self on my next puzzle.  Maybe.

I was recently walking with coworkers on lunch break and they were saying how much they like word puzzles and sudoku.  I can do the word puzzles but find sudoku too stressful.  I much prefer brain teasers.  So I told them about this one.  Unfortunately for them I I didn't give them the answer as they must wait until Monday to get it.  So here is your test...

Imagine you are in a room with 3 switches.  In an adjacent room there are 3 bulbs in seperate lamps, each switch belonging to one bulb.  All are off at the moment.  It is impossible to see from one room to another (no you can't see any residual light if you leave the doors open too, besides it wouldn't help anyway).  No help from anybody else is allowed (only you).

How can you find out which switch controls which bulb, if you may enter the room with the bulbs only once?

Haha.  I'll post the answer on Monday.  BTW, all laws of physics apply and it is possible.

Well if you look at the math by trying to break up everything evenly it won't seem to make any sense, but if you work backward it will come together.  Take the boys $2 and add that to each of the $1 given to the three guests then add that to the $25 given to the manager and you have $30.  OK, I know what your saying, it still doesn't solve the problem of each of the guest paid $9 dollars which equals $27 and the boy only took $2.  Well if you think of it, you can't equally divide the$25 room rate into 3.  So in the scheme of things, their extra dollar gets mixed in with the $25 because 3x8=24 and not $25.  So they technically paid $8.33333333 cents.  Haha.  Did you get it?

Xeyli was on the right track.

Well being Friday and all, and since I don't usually post over the weekend I leave you all with another brain stumper.  It's not as intense as the Eienstein puzzle but still fun and baffling to figure out.  In some ways it sounds familiar like I heard this one before but I still couldn't answer it on my own.  My hint to you...think out of the box.  Good luck Voxers, I'll post the answer on Monday.

You have three people who check into a nice Italian Hotel.  They give the manager $30 and proceed to their room.  The manager finds that he can offer them a discount and that they only needed to pay $25.  The manager then gives $5 to the bellboy to return to the guests.  On the way to the room, the bellboy figures that he can't split $5 among the three people so he pockets $2 and therefore gives $1 to each person.  Now each person paid $10 and got back $1.  So they ended up paying $9 each, totally $27.  The bellboy has $2, making the total $29.  Where did the remaining dollar go?  Is it even possible?  Anyone have an answer?

So your a Vox blogger or in the least a lurker.  If your visiting this site, it tells me that your a very intelligent and beautiful person.  Since I don't blog over the weekend, I wanted something to keep you busy and guessing what the answer is, especially when it's a challenge by the one of the greatest minds in history.  Read on...

Einstein_tongue.widec

This quiz was probably made up by Albert Einstein and according to him 98% will not solve it.
There is a row of five houses, each having a different color. In these houses live five people of various nationalities. Each of them nurtures a different beast, likes different drinks and smokes different brand of cigars.

1. The Brit lives in the Red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The Green house is on the left of the White house.
5. The owner of the Green house drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the Yellow house smokes Dunhill.
8. The man living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The man who smokes Blends lives next to the one who keeps cats.
11. The man who keeps horses lives next to the man who smokes Dunhill.
12. The man who smokes Blue Master drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the Blue house.
15. The man who smokes Blends has a neighbor who drinks water.

Which of the five house owners keeps fish as a pet? (are you one of the 2%).

Well?  Let know know what you think is the answer.  Take your time, you might be part of the 98%.  If you truly solve the puzzle on your own, I will be greatly impressed.  BTW, I will post the answer on Tuesday (Monday's a holiday).
