You selected the correct response (you must have your Doctorate of Bubblology).

Question 1 of 1

Which of the following is not true?

• The bubbler system clears duck weed from the surface in much the same manner as a diver’s exhaust bubbles do.
• The compressor that powers the bubbler system has been modified to put out considerable volume (just not a lot of pressure).
• The bubbler is unnecessary when divers are using open-circuit scuba, as their exhaust bubbles will be sufficient to keep the surface clear.
• Once the bubbler system is activated, we can control where, and in what volume, air comes to the surface.
