Learn with your Shower Curtain

I just had to share something I just came across online. I have never seen it before, but it's the Top 100 SAT Vocabulary Shower Curtain .

Basically, it's supposed to help your child by exposing them to the Top 100 SAT Vocabulary words every day when they take their shower.

I wonder how effective it actually is. It doesn't look like there are any definitions. So is it any good to "know" the word, but not know what it means or how it's used?

Would you buy this shower curtain for your child?
