go down fast
Depth Charge
• tall pint glass of Beer
• shot of  Bourbon

Shout "Akikazi off the Bungo Straights. Dive. Dive!" Then drop the shot of bourbon into your pint of beer.

Open all vents.  Put the dive bubble on your glass at max. Take it down the bottom.

You may have to send up clothing thru the torpedo tubes to fool the enemy into thinking they've got you.

Resurface when ready to battle again.

Warning: Coming up too fast can cause the "bends."
