The Problem with the Hourglass

Some students have to take a test in 9 minutes. Due to an electromagnetic pulse, every watch has stopped working and we only have two hourglasses to measure time.

These two hourglasses (the only ones we have in the high-school) last for 7’ the first one and 4’ the second one. 

How can we measure exactly 9 minutes (neither one second longer, nor shorter) using these hourglasses?

Tip: try to start both hourglasses at the same time. What happens after exactly 4 minutes?

Deadline: October the 25th.

Printable version available.

And we continue with the 90's...

Ismael's Problem

Ismael visits a one-floor castle with 64 rooms connected as described in the image below. He starts in the bathroom (the black square) and since he feels sooooo relieved he wants to visit the 64 rooms using only 15 straight lines.

Would you be able to help Ismael and draw a path for him starting at the balck square and using only 15 different lines ( without removing the pencil from the sheet) so he manages to visit the 64 rooms?

Watch it: You MUST start your trip from the black spot, but you can finish it wherever you want. Notice there’s one missing connection between two towns at the bottom of the drawing. 

Deadline: October the 11th

The Problem with The Sports

We move from the peaks of the Pyrenees to the Valley In 6 months some of you will face some of your worst fears in the Green Week (heights, rafting, arborism, rappelling) Let’s see if you manage to survive those hazardous situations!

If we analyze what happened last year, I was in charge of 30 kids

- 16 of them did the Rafting Activity, 14 of them the Rappelling activity and 13 of them the arborism activity.

- 6 people did the Rafting and Rappelling activities, 6 people took part in the Rafting and Arborism activities and 5 people enrolled in the Rappelling and Arbosim activities.

- Only 3 people had enough courage to do the three activities.

Well of course there is no doubt that I did them all!

The question is how many of those 30 kids didn’t take part in any activity?

Extra Question: who is hiding behind the mask?

Deadline: October the 4th

The Problem with the Pills

Last year’s white week was a great experience, but Elena and I needed some help to cope with all your daily crazy stuff That’s why the doctor prescribed us some pills to both avoiding getting nervous (Pills Type A, blue bottle) and preventing us from feeling dizzy during the day (Pills Type B, green bottle). We had 6 pills of each type (one for each day) and all of them looked and tasted exactly the same.

The problem is that on the first day I dropped them accidentally and two B-pills and one A-pill fell from the bottles and I couldn’t tell which of those three pills were the two B-pills and which was the A-pill!

I was terrified because the doctor had told me that if by any chance I would take by mistake 2 pills of the same type, I’d go crazy-bananas and all your grades could be changed to zero without even noticing what a disaster!

Anyway, that didn't happen...

So... how did I manage to take the proper dose every day? (one type-A pill and one Type-B pill)

Deadline: Thursday the 27th of September
Hand in your solution: you can either send your solution by e-mail or hand in a handwritten copy next week.
There is available a printable version.

Have a nice weekend! 

This song is from one of the first CD's (there was a time when people used to buy CD's, cassettes, vinyls...) I have ever bought in my life (I was 13 years old).

Harlem Shake

Hello everybody! As you all know, Harlem Shake is becoming more and more famous.
In the first nine days of the phenomenon over 11,000 dance versions were uploaded to YouTube and it's calculated that about 4,000 new versions of the dance are uploaded each day.

Harlem Shake has been covered from planes in flight to squads of armies, like this, for example:

Many people have made their own version of this dance, so we decided to make our version too. This is only a trial, we will make the definitive video in a few days.
Meanwhile, here you have our Harlem Shake! We hope you like it:

Rhombic dodecahedron calendar 2013

Here's a little thing you can easily build in less than hour :D

The calendar is just one of its multiple uses... If you prefer, some pictures could be printed in each module so you'd get a collection of pictures instead this year's calendar...that's your choice!

These are the templates for the Calendar:

It is very easy to build this figure with your own pictures placing them using the following model:

And finally, but not less important, some instructions, both for the module and the final assembling:
