water. oil. food coloring. a few clear glass jars. a lot of imagination and voila! you have floating rainbows. this is best done outside as it can get messy. however, in the end this was a short-yet fascinating little chemistry lesson. science words for very young scientists: sink. float. layer. mix. separate.
thank you : more mudpies to magnets because they are itching to do more “experiments” and these are very easy, which always makes me very happy!
