|how many hands?
On 30 November 2009, Nance Klehm led her Northwestern students in an excavation of a rock covered in half a century’s-worth of paint layers.
the original e-mail invite to the Northwestern students-
CORE SAMPLE – BLOW HOLE
at ‘The Rock’
please bring an exacto blade w/extra blades, a knife, a sanding block with extra coarse paper and help excavate through decades and decades of colorfully painted advertisements of this everlasting gobstopper to reach its ice age heart.
how many hands and how much time will it take to get to the core of the matter?
