The F Word

FINISHED FILES ARE THE RESULT OF YEARS
OF SCIENTIFIC STUDY COMBINED WITH THE
EXPERIENCE OF YEARS.

Now count the F's is that sentence. Count them ONLY ONCE.
Do not go back and count them again. Then see below:


There are 6 F's in the sentence.
How many did you count?

How I Would Use This

For fun I could turn it into an intelligence test.

Another idea is to use it to illustrate how often we make assumptions. The brain assumed that the V sounds were just that, V's and not F's. We make hundreds of assumptions daily, some are harmless like this little activity, but some are not harmless at all.
