Looks like touch2solution.gif shows 7 matchsticks (pencils). Pretty impressive.
If you look closely at the Touch2Solution you will see that the "RED" and the "LIGHT BLUE" match are "NOT TOUCHING"! The Thickness or mass of the "DARK BLUE" match is seperating them from touching. It may Appear that they are in contact from an ariel view, however it is obvious that anything with mass is going to seperate 2 objects if it is between them.
Tell me what you think about my findings. I'm open for debate!

There ya go. Perfect!

Well that's because that's a pic of pencils not matches.
But seriously, if they were wooden matches and not pencils and you replaced the red pencil with a match that had the head of it facing to the right, it could be placed so that the bulbous head of the match is in contact with the light blue pencil.
But I see what you're saying. The solution with six matches is much more elegant in that it doesn't have any matches (pencils) on an incline possibly not coming into contact with others. crescent_tr's solution suffers the same problem (and since he/she used what looks like six-sided markers [similar to yellow pencils], this could probably also be remedied by turning the orange tipped marker so that it's resting on one of its six high points). Six is the maximum number of wooden matches or pencils that can accomplish the goal of having them all touch one another without using inclines.

sharpen pencils and touch them in a point!
That won't work. The pic below just gives the illusion that this solution will work. Let's say you start this arrangement by putting the points of the black and yellow pencils together. In order to place the green and blue pencils together so that their points meet, the barrier made by the points of the black and yellow pencils must be broken. A configuration of this type can't work with more than three pencils.

This looks like the answer
The four crossing in the center are apparently stacked.
How can each touch the other three?
