STEP 1: Remove any spiders from the bathtub. They may adversly affect the effectiveness.

STEP 2: Fill the tub with water until the depth is about 7cm (the metric system makes your death more accurate and easier to calculate). Place your instruments of death next to the tub.

STEP 3: Get in. Even though there is shampoo right next to your head, ignore it. You're here to die, not get clean. You can sponge off your armpits though.

STEP 4: Drop the battery in.

If that doesn't work, or you are too impatient to wait for the single battery to work: dump in a whole handful of batteries. Throw in some 9 volts if you got 'em, go nuts! The key is to have fun with it.

STEP 5: Read your magazine while waiting for the current to kill you.
