Slime Design...  

   Where to start?

   Oh, yes... In the beginning, God created the heavens and the earth.

   Then He made snails. 

   Engineers at Penn State created a super-strong, yet reversible adhesive to mimic snail slime, which offers a happy medium between superglue and not super sticky. 

   Snails secrete a wet, gooey substance that on a dry day works its way into microscopic pores, even on smooth surfaces, where it hardens. It cements the snail in place, creating a seal that prevents the snail from drying out. 

   At night under wetter conditions, and safer for the snail, the substance softens and allows the creature to move. 

   Researchers developed something (with a name longer than the snail) that mimics the ability of snail goo. A patch the size of a postage stamp can hold the weight of a researcher suspended by a harness, yet still releases its grip when wet.
