Tongue Rollers


your results

Sent in by:
Aaron of Bozeman, MT

Be part of a live, international science experiment right here. We want to know if an equal number of boys and girls can roll their tongues.


Can you do it?

Choose the button that matches you and click it to add yourself to the tally:

We can see that 40% of boys surveyed can roll their tongues and 85% of girls can roll their tongues.

Of the total, 73% can tongue roll and 27% cannot.

Is there a pattern you can identify? Can you explain the pattern? Now, go count how many of your friends and relatives can roll their tongues. Click once for each person. Tell us whether they're boys or girls (men or women too) and if they can tongue roll. The page will come back with YOUR totals included.

This is a genetic trait inherited from your parents. If both of your parents can not roll your tongue, then there is no way that you will be able to do it. I f one of your parents can roll there tongue then there is a 50 percent chance you will be able to. If both parents can perform this than there is a 25 percent chance you will be able to rol your tongue. Sadlty if you can't do it, there is no way how to teach yourself how.

I did it while I was watching the results for the people who could roll their tongue and who couldn't roll their tongue... but BEWARE... if you do it too much, your tongue will hurt. Badly. because my tongue hurt when I rolled my tongue too long.

i was able to roll my tongue. it is a genetic trait. the ability to roll your tongue is dominant. this is what my dad just told me.

I did it right away. It is very fun to do. I read in my science book that it is a genetic thing. There are also many other genetic things like if you have a straight hairline or a widows peak, or attached or unattached earlobes.
