What do they put in that?

What do they put in the Magic Eraser to make this thing so amazing??????!!!!!!! Seriously, this thing rocks. I did not worry too much about the kiddos coloring on the floor and walls at Eglin because we lived in government housing and I was going to have to repaint every room anyway when we moved. But here....well, I am a bit paranoid. We have all white walls and the landlord lives across the street. Paulie is way into coloring and sometimes sitting in his highchair just does not cut it anymore. He wants to color on his little table and the easel...and honestly, when he sees William doing it I can't blame him for wanting to be like his big bro. So this morning as usual, Paulie is crying over near the crayons and markers because he wants to color....and well, a small amount of purple marker makes it on the white walls. But, WA-LA, no problem when Magic Eraser is here to scrub it off...and without much elbow grease. Gotta love it!
