[Scuba diver breathing]

A scuba diver swims around a coral reef among a horde of fish.

A narrator says, AH, SCUBA DIVING.
GREAT, ISN'T IT?
BUT NOT AS EASY AS IT LOOKS,
AS WE'LL FIND OUT WHEN
WE DIVE INTO
THE TOP ON SCUBA DIVING.

A title reads, Top on Scuba Diving.

The first narrator says, WHEN SCUBA DIVING, YOU SHOULD
ALWAYS KEEP CALM,
AND NEVER COME UP TO THE
SURFACE TOO QUICKLY.

An animation shows a scuba diver rising through water.

The second narrator says, WHEN YOU BLOW UP A BALLOON
AND PUT IT IN THE WATER,
THE WATER PRESSURE WILL
SQUISH ITS VOLUME.
THE DEEPER YOU GO IN THE WATER,
THE MORE IT'LL SHRINK.

An animation shows a blown up balloon shrinking as it travels deeper into water.

[Balloon deflating]

The second narrator explains, VICE VERSA IF YOU INFLATE A
BALLOON UNDERWATER
AND LET IT RISE TO THE SURFACE,
IT GETS BIGGER 'TIL IT POPS.

In the animation, the balloon rises, then pops.

[Balloon popping]

The first narrator says, IN THE WATER,
OUR LUNGS ACT LIKE BALLOONS.
IF YOU INFLATE YOUR LUNGS
DEEP IN THE WATER AND RISE UP
TO THE SURFACE TOO QUICKLY WHILE
HOLDING YOUR BREATH,
YOU CAN CAUSE SOME
SERIOUS DAMAGE.

The animated scuba is shown flailing in the water.

The second narrator says, THAT'S WHY IT'S
IMPORTANT TO STAY CALM
AND REMEMBER TO GO UP SLOWLY,
LETTING THE AIR OUT OF YOUR
LUNGS AS YOU GO.

The first narrator says, HELLO, MR. ORCA!

OF THE DEEP ARE CAUSED BY
THE TOXIC EFFECTS
OF INHALING NITROGEN.
ONCE YOUR HEAD'S ABOVE WATER,
YOU CAN BREATHE MORE EASILY.

The first narrator says, IF YOU WANT TO TAKE THE PLUNGE
INTO SCUBA DIVING,
YOU'VE GOTTA BE HEALTHY,
AND LIKE THIS GUY, STAY CHILL.
