Brainteaser Tuesday

Here's some fun that also works our brain.

Tuesday is our official Brainteaser day. Each week I'll post some new puzzles, riddles or brainteasing game of some sort for you to figure out and work YOUR noodle.

Growing evidence suggests that a lifetime spent using your noodle — in your day job as an astrophysicist or mom, or after hours playing Monopoly, tooting the clarinet in your local chamber group, or doing crossword puzzles — may build extra brain connections (a kind of mental savings account called cognitive reserve) and slow the symptoms of dementia.

We'll start slow this week. Here's a couple riddles for you to get going:

  • What gets wetter and wetter the more it dries?
  • You throw away the outside and cook the inside. Then you eat the outside and throw away the inside. What did you eat?

Please share your answers with us in the replies.

well, I'm glad to hear I stumped SOMEONE!! LOL :D

I'm going to have to find something that takes a little longer to figure out.
Andie_WebMD_Staff replied to Andie_WebMD_Staff's response:
You are standing in front of a room with a light bulb inside of it.

You can not see if it is on or off.

Outside the room there are three switches.

You may turn the switches anyway you want to.
You stop turning the switches, enter the room
and know what switch controls the light bulb"026

How do you do that ?
Lupylisa44 replied to Andie_WebMD_Staff's response:

Question: can you enter the room more than once?

turn the first and third (or any combination) switch on...enter the room. if the light bulb is cold then it's switch #2
lisaisweavebee replied to Lupylisa44's response:
but if you enter the room and the bulb is on then all you know is it isn't switch #2...
lisaisweavebee replied to Andie_WebMD_Staff's response:
I know the answer! (But I cheated and got a little help)
Lupylisa44 replied to lisaisweavebee's response:
Oh! I don't brain hurts!!! LOL
lisaisweavebee replied to Lupylisa44's response:
The answer is: turn on switch one and wait five minutes - then turn it off and turn on switch two and immediately enter the room. If the light is on, it is switch two. If the light is off but the bulb is warm, it was switch one. If the light is off but the bulb is cold than it is switch three. My only question is - what if the bulb is out of reach? ha (being only 5 foot tall, this happens to me a lot!!)
