Oh no!!
Forever Alone has given up his will to expend the whole eternity alone and has decided to take every single kid studying 1st or 2nd of ESO, among whom there are some of your siblings...
Damnable!
The instructions he has given to set them free are the following:
1) I promise half of them will be released if you solve the following simple challenge:
The snail's journey
A
foreveralonesnail has fallen into a 12meter deep pit. Lucky him, this
pit was not filled with water, otherwise this fellow snail would be
foreveralone dead.
After two days
waiting for a rescue, he makes up his mind and decides to try to get out of the
pit singlehanded. During the daylight, he manages to climb 2 meters, but when the
night time arrives, he rests and therefore slips 1 meter backwards.
How long will it
take for the snail to reach the surface?
2) All the hostages will be released if your brain manages to sort out the following situation:
The Three Hats
Three
foreveralone prisoners have bribed the guard to let them run free. However,
when the time comes, the guard decides to add one extra challenge:
“I have here 5 Mexican
hats: 2 black hats and 3 reddish ones.
You will be set
in a single line and three hats will be put over your heads. This way, the
person standing at the back can see the second person and the first one (and therefore
their hats), the person who is placed in the middle only sees the person
standing before him (and his hat) and the first one can’t see anybody.
Some questions
will be asked and your freedom depends on some of you to give the right answer.
In the event of failing all the questions, you should be here forever and
foreveralone with me”
The guard
started:
 “This question
if for the guy in the back”. What’s the colour of your hat?”
 “I don’t know”, the prisoner replied.
 “OK. You, the
second one. What’s the colour of your hat?”
 “I don’t know”, the prisoner replied.
 “Muahahaha!!!!
You’re bound to be here with me for all the eternity!!!! Last chance! You, the
first one, will you be able to guess the colour of your hat?
 “I have a red hat”, she stated.
And
the prisoners were released.
How did the prisoner in the first
place of the single line guess the colour of her hat?
"This are the challenges you have to face. Shall my commands not be met, a disaster beyond your imagination will occur"
Euler Piruleta's services have been required once more to try to fight the maths terrorism!! But he needs your help!! Each challenge will be rewarded with one positive but be careful, Forever Alone's deadline is November the 18th... Do not hesitate and help Euler Piruleta to release the children!
Will Euler Piruleta manage to defeat evil Forever Alone? He has decided to relax with some music before the struggle:

Don't miss the lyrics XDD
Nothing better to relax than a good laughter with a hilarious film. This has been my best contribution to youtube so far: 23.000 views. It was created in a library 4 years ago an afternoon when my brain was begging for a scapeway...
