Do you tap the top of cans before opening them?

Do you tap the top of a soda can before opening it? Do you know anyone else who does? Do you even know what the theory is behind why it is supposed to stop the can from frothing when opened? Do you know where the theory came from? Did you know it may even do more harm than good?

If you would like to know the answers to these questions then look no farther. What I would really like to see however is someone engineer a way to indicate to the user (opener, whatever you want to call them) what the potential is for the can to explode upon opening.
