Walk in a Spider’s Shoes

To catch its dinner, a spider spins a sticky silk web for unsuspecting insects to land on. So why doesn’t the spider it’s self

get stuck? One theory is that it covers its feet with an oily liquid. To see how it works, rub a bit of shortening on your finger tips. Place a long strip of tape (sticky side up) on a table. Use shorter pieces to tape down the ends. Now you can easily walk your fingers the length of the strip.
