True or False: If the mouthpiece is out of your mouth, you should continuously exhale a small stream of bubbles.

Explanation:
Keep breathing continuously. If the mouthpiece comes out, exhale a steady, light stream of bubbles. This keeps air moving so you aren’t holding your breath, helps prevent water from entering the mouth, and aids buoyancy by venting any air you’re not using. The visible bubbles also signal to your buddy that you’re breathing. Holding your breath is dangerous underwater, and not exhaling could lead to air being trapped and potential problems when you reinsert the mouthpiece.
