3. Electricity

It is a well-known fact that Spiderman is vulnerable to electricity. He has been zapped by the Shocker as well as Electro, and that is not something good for the superhero. So, one could possibly say the Spiderman would have to keep away from anything to do with electricity as and when he happens to be dealing with trouble. Otherwise, it is a documented fact that Spiderman would have to make use of every inch and every fiber of his body to get away from that position or else he would become a frying person, and not a flying one.
