I want to make our family room fun for us and the kids so I decided to get us Orbeez mood lamp. It's a ball that comes in different color, when you add water to it becomes bigger 100 times its size. It is fun for the kids and us and it glows in water. You can always go to their web site to Buy Orbeez refills in different colors. The kids love to play with them, they make different designs. It is really fun to have orbeez so get your now.
