How / to split / your own tongue

Things You'll Need:
•       Fishing line

Step 1

Pierce your tongue and allow it to heal fully. Full healing can take up to a month. A pierced tongue is absolutely necessary when you split your tongue yourself.

Step 2

Ensure that you have a high tolerance for pain. Splitting your tongue yourself takes several weeks and the procedure involves a lot of pain.

Step 3

Take a fishing line and thread it through the hole where your tongue was pierced. Line the fishing line up with the tip of your tongue and tie a knot in the line as tight as you can bear. Tie a second knot in the line so that it's so tight it hurts.

Step 4

Repeat Step 3 every 3 to 4 days. The line should be loose after a few days so you can cut it off and replace it.

Step 5

Continue the tying process until your tongue is almost fully split. It will take between 4 to 8 weeks. You may have to use a razor or blade to cut the last little section of tongue.

Step 6

Practice using your newly split tongue. You will soon be able to move each section individually and be able to talk without a lisp.
