For the cost of your favorite Gatorade or soda, you can not only save the planet by reusing the bottles, but also give Barbie her very own boat for all of her water adventures.
I just cut out a place for them to sit and with electrical tape (you could probably use something cuter if you wanted) you connect them together and there it is. One of the most inexpensive, yet highly excitable toys. you can make.
My girl is gonna love it!!
