What the FRACK?!
[This was written by Fran Siebrits and published online by Hy-Se-Sy-Se www.hy-se-sy-se.com/what-the-frack, 2011]
Hydraulic fracturing (fracking) is a method of extracting natural gas and oil from the layers of rock underneath our feet. A phenomenal amount of water, mixed with a shocking variety of chemicals with unpronounceable names, is forced down a pipe that has to first be drilled into the earth. The pressure of this action forces the liquid concoction into cracks in the shale layers of the rock, dislodging and releasing pockets of trapped natural gas and oil wells.

Orb-weaving spiders do not construct silky patterns only to catch their prey, but also as a means of reacting to web damage.
Flap, Run, Fly
