Yep.

[BadgeAddict]

Okay, here goes:

You are in a 2-story house; on the wall there are three switches labeled 1, 2 and 3. Upstairs is a light-bulb that is turned on by one of these three switches. How can you figure out which switch turns on the light? Rule: You can only go upstairs once to check. (there is no cheat to this, such as walking outside to look upstairs or looking for light up the staircase)

[Arch Lich Burns]

Get another person to flip the switches one at a time.

[I'mBob]

I turn on switch number 1, wait a few minutes and then turn it off. Then I light switch number 2 and go up.

If the light is on, It's switch number 2.
If the light is not on, I touch the bulb, if it's hot then switch 1 is the right switch since I opened it and waited enough time for it to get heated. If the bulb is not hot, then it must be switch number 3.

(Unless they are LED bulbs or something and them I'm wrong)

And I have 1 riddle which is pretty hard:

You have 1000 bottles. One of them is poisoned with a colorless, smell-less and tasteless poison, the others are water.
You use bunnies to check the bottles, you need to find which bottle is the poisoned one.
You pay 5$ for every bunny you use, so you would want to use the least amount of bunnies that you can.
The poison does not affect immediately.

I want an answer with an explanation.

[lingrem]

I would only use one bunny. No one said I had to figure out which one the poison was right away. So I'll give the bunny one a day and see if there's any affect.

[I'mBob]

Okay, smartass you need to figure it out in 24 hours. The poison takes effect after 23 hours.

[lingrem]

Sorry, you didn't specify that! I WIN!

[I'mBob]

Sorry, you didn't specify that! I WIN!

Fine, her is your reward:


I expect you to use this gift, and you will deeply hurt my feeling if you wont.

Also, I just noticed your answer is wrong, what if the poison takes effect after a week? a year? a month?

[Arch Lich Burns]

That stache looks horrible for multiple reasons.

You have 1000 bottles. One of them is poisoned with a colorless, smell-less and tasteless poison, the others are water.
You use bunnies to check the bottles, you need to find which bottle is the poisoned one.
You pay 5$ for every bunny you use, so you would want to use the least amount of bunnies that you can.

None of them are poisoned.

Why? Because I dumped them all on the ground.

[I'mBob]

Now you just ruined the last water resort of the universe, and every people in the world will die cause of you! Look what you've done.

[lingrem]

Also, I just noticed your answer is wrong, what if the poison takes effect after a week? a year? a month?

But you just said it takes affect within 23 hours. If it took ages for it to take affect, then I wouldn't be able to come up with a solution that quickly anyway.

[I'mBob]

Stop being a smartass!

[gamecreator]

To detect poison we will need 10 bunnies. First, number those bottles from 1 to 1000 and bunnies from 0 to 9. Then for each bottle convert it's number to binary and give drink from that bottle only to those bunnies, whose number corresponds to "1" bit. For example, from bottle 984=1111011000 will drink bunnies 9,8,7,6,4,3. When bunnies will die from poison, reverse coding procedure: take numbers of dead bunnies and set corresponding bits to 1 and other bits to 0. Convert into decimal to get number of poisoned bottle.

Yeaaa riiiiiiighhht. And if I did keep those bottles they'd still be dead. Actually I have a better idea.


Pour water into trough. Then put back into the bottles. Now every one of them is poisoned! Yey poison! ...You didn't say we have to save people, just which one has posion.

[gamecreator]

Better to empty and wash all bottles and fill them with clean water.

[DrinksTooMuchCoffee]

Buy one male bunny and one female bunny and then wish you had more poison.

If all of the bottles contain water, then simply find the bottle that does not contain water.

To clarify what you said: You have 1000 bottles. One of them is poisoned with a colorless, smell-less and tasteless poison, the others are water.


Therefore, 999 bottles contain water, one of them does not. You have 1000 bottles, one of them is poisoned, you did not state that the poisoned bottle was filled with water.

Thus, find the bottle that does not contain water.

Huh? The bottle that have no water have the poison, he is not filled with water, but with poison. and the whole riddle is about finding it.

[BadgeAddict]

I think i just dropped my brain and then proceeded to trip over it.

[gamecreator]

I even know what poison is in that one bottle. It's hazardous dihydrogen monoxide.

Btw, Bob, check out my solution. I think it's correct.

Nope. It's not.

I will give you a hint:
The answer IS a number which is not 0 or 1.

[M0rtimer]

No worries Bob, I'm here to save you from all these smartasses.

You need 65 bunnies. You proceed to make 25 rows of 40 bottles, which equals 1000 total. You then assign each bunny to a row- 25 taking horizontally, and the other 40 taking vertically. They will all take a drink of each of the bottles on their row.

In the end, you should have two dead rabbits, one from the horizontal row and one from the vertical. That will tell you which of the bottles was poisoned.

At least I think 40*25 is the optimal configuration.

I haven't done the math on game creators one, but it could possibly be correct. Better then mine at least.

If this is wrong: Sorry Bob! I failed to save you from the smartasses.

[gamecreator]

The answer IS a number which is not 0 or 1.

Well, I wrote that answer is 10 bunnies. I don't see any contradictions.

At least I think 40*25 is the optimal configuration.

Actually optimal configuration is 32x32, as square is known to have the least perimeter of all rectangles of constant area.

Yeah, your right actually. Though I was focusing on the "exactly 1000", that configuration would even leave some excess space.

That being said, it's only one bunny.
