(a.k.a. How to get your kitchen floor really clean)
The kitchen floor was a mess. I never could figure out which pair of shoes leave all of the annoying scuff marks, but they were all over. Usually I use a Magic Eraser to get up the scuffs. Ethan was very excited about cleaning the floor, but I was out of Magic Erasers. I figured that any cleaning was better than nothing, so I told him to have at it. I forgot that he was a experimental scientist. I knew that we was using windex. I said ok to the small amount of dishwashing soap he was using. I stepped into the other room listening as he worked and talked on the phone. The first warning I had was "Mom, you don't want to come in here! It's very slippery." OK, I say and continue my conversation for a few more minutes. When I get up to check on him, this is what has become of the kitchen:

The kids had a blast skating on the bubbles. (Annelise was not thrilled with the several times she fell down, but she always got back up :) After a few minutes of letting him play in his masterpiece, I got a big towel and started to dry the floor (after changing Annelise and putting her in a no-slip zone). I was shocked to find that Ethan's mixture cleaned the floor better than any of the mopping stuff I use. I sent him over all of the serious dirty spots and mopped up behind him. The floor is clean and the kitchen smells all lemony.
Now, if only he would invent a new way to wash all of the laundry this adventure produced....
