To make it extra special, I bought Magic Marbles to play with in the table. What are Magic Marbles?? Well, they are a neat little product than start very small, and when water is added, they "magically" turn into a gel marble. Gel crystals that are the same concept have been used for years in the florist industry. If you ever had a lucky bamboo plant stuck in a gel substance, it's the same type of product.
What I like about these marbles are they are fun way to teach science, predicting skills, and just plain fun. They last a long time, can just be rinsed in water if they get too dirty, and when you are done playing add them to your soil to keep the plants hydrated.
I bought mine from QVC from the Roberta's product line. I received five tubes in various colors for under $20.00. Each tube will make five quarts of marbles. So it will easily last the whole summer. Here's a few pictures of them.
