We had our own experiment to make freckle juice. The experiment consisted of mom finding every fruity or sugary item in the pantry that we could mix into a cocktail and actually drink. I ended up with a variety of sprinkles, mini-marshmallows, several flavors of kool-aid juice jugs, strawberries, lemon juice and lollipops to stir it all up.
Sounds disgusting, I know, but it was amazing how into their concoctions the kids got. The best part was that Alan came home from work during the middle of all of this. Hearing what the kids were doing he ran upstairs and put make-up "freckles" on his face. He came down and pretended to drink some before the kids noticed him. As they looked up and saw his face their jaws dropped and they all became speechless, looking slightly frightened. OH NO! Their freckle juice had worked! Dad washed his freckles off just like Andrew Marcus had and you could tell that was on their mind for the next few hours because at bedtime they timidly asked if that had really happened. I told them our little joke, which they didn't see the full humor in given the scare it but them through. Hey, Alan and I have to do some things around here to keep it fun for us too:)
Bottoms up!
