You have at your "disposal" four of those fancy new-fangled compasses and an ultra-modern straight edge and a piece of ordinary bright white twenty gr/m2 bonded letter-size paper. The compasses, being the latest and greatest, draw perfect arcs with both point and pen remaining perpendicular to the drafting surface and the pen drawing with the finest imaginable line weight. They are also infinitely adjustable to the nth degree. Of course the one downside to being so new is that once an arc is struck, the adjustment mechanism is permanently frozen. Now the straight edge is also of the most modern material and is straight on an atomic level; that is until you attempt to draw a twelfth line, at which point some bizarre reaction with the compass' ink or the space age alloy of the metal point irreparabably warps the patented polymer used, rendering it useless (research is now fully funded and ongoing to determine if it's the ink or the metal).
The objective of this challenge is to draw a perfectly regular five pointed star using only what's contained in your body and in the above discription.
