The ultimate challenge.

Put soda in your mouth and don't try to make it so it doesn't touch the tip of your tongue.
Hold it there for at least 30 seconds.

 

I can't drink soda, how do you do it?

 

This thread is about a challenge, not dental hygiene...

 

You get the soda. You put the soda up to your mouth. You put a little in your mouth. You swallow the soda. You put the soda away.

 

It burns my tongue because of carbonation though.
