My mermaid granddaughter

My ten year old granddaughter loves watching this Australian TV show about mermaids.  She desperately wanted to get this mermaid swim tail to use in the pool.  After getting a good report and the end of the school year, my daughter surprised her with it.
She zooms from one end of the pool to the other with the help of this mermaid fin.  I have to say it looks like fun.  It gives your abs a good workout too.  Still, I don't know I would like being so confined with my legs stuck together in the swimsuit part of it.  Don't worry, I'm not going to try it hahaha!  I'd probaby end up yelling for help!
