Sliding cards brain buster

November 29th, 2006

Wow, I’m still having a hard time wrapping my mind around this one…

A real brain buster created by Marcel Debreuil:

Think you can solve this? It looks simple but the more you look the trickier it gets.

The idea is there are three panels - by switching the top two around you get two pictures. The catch is that although the figures line up, there are a different number of people in each of the two resulting pictures. Below is one I made 15 years ago (man!). The first picture has 13 people, the second only 12. For an extra twist, one person has turned into a fresh steamy dog turd. So the question then is, Who turned to doggie doo?

3 cards separate
“These are the 3 pieces of the puzzle- the top 2 can switch around to make the images below”
3 cards together part A
“Thirteen people, you can count them”

3 cards together part B
“Twelve people, but the dog was busy. So who turned to doggie doo?”

Will post the answer in the comments section in 1-2 days;

A new study done by Scott Hemby and colleagues at Wake Forest University of Medicine finds that long term cocaine use leads to “profound changes in brain function”.

Cocaine, Ritalin (amphetamines), and coffee all work differently on the brain, but in the end, they are all stimulants, and they can all induce euphoria by modulating the amount of the neurotransmitter dopamine.
I suspect it’s just a matter of time before research shows that long term consumption of coffee also leads to “profound changes in brain function”.

Will people find this suprising? Will they care enough to modify their consumption?
