Lesson 2 (using simple valveless snorkel):
1. With snorkel in mouth, dip head under water till tube fills with water.
2. Raise head back to surface.
3. Blow sharply to clear water out of snorkel.
4. Next inhale should be slow and steady. It's possible there will still be water in the curve but the air will bubble through.
5. Repeat steps 3 & 4 until tube is clear of water then revert to step 6 of Lesson 1.

Actually there is a legitimate question here and, sarcasm aside, there is a bit of physics behind why a snorkel is like it is. I'm not going to reinvent the wheel explaining it because Fizziology is already very well explained HERE. 
Does this help explain the what you want to know, rna?

Tube diameter also has something to do with the physics as well.
Nice site CBulla! Its written simple enough so that even someone like ME can understand it. I added it to my favorites.CBulla:Actually there is a legitimate question here and, sarcasm aside, there is a bit of physics behind why a snorkel is like it is.

There is a compromise involved in tube diameter. A larger air will allow more airflow with less restriction, but the internal volume of the snorkel is another dead airspace (along with your mouth and throat) that you have to overcome to move air in and out of your lungs. So too small a tube diameter increases breathing resistance while too large a tube diameter negatively impacts efficiency in getting oxygen to your lungs and in getting carbon dioxide out of your lungs.
Snorkle lenght also effects the volume of the snorkel so a longer snorkel will also have more dead air space to overcome. Pressure effects aside, longer snorkels would not be practical as the longer the snorkel, the less efficient it would be until you reach the ultimate lenght where your lungs lack the volume to move any useful amount of air through the tube.

Welcome to the board.
Snorkels are simple. to clear one you get to back to your 5th grade juvenile deliquent days...pretend you are thry to shoot a spit ball at your buddy from across the room when the teacher's back is turned.
