Bad Idea #6 - You have to shake Gatorade because the electrolytes will settle to the bottom.

This one is courtesy of a mutual friend, who we shall call Encarta, who told me about this exchange during a drive:

Encarta - "Why do you shake your Gatorade every time you take a sip?"
Roommate -

6. "I shake Gatorade before I drink it because the electrolytes settle to the bottom."

Electrolyte: A substance which forms ions in an aqueous (water) solution (source).
Solution: A homogeneous mixture composed of evenly distributed solute particles in a solvent (source - scroll down to encyclopedia portion).

Bad ideas, meet poor understanding of basic chemistry.
