We were inspired by the Tubtime Crayons recipe in The Ultimate Book of Kid Concoctions. We started by grating a bar of Ivory soap and adding it to 1/4 cup of warm water. After stirring it, we separated the slippery soap 'dough' into 4 parts and added about 5 drops of food coloring to each part.
We popped the soap into the freezer for about 10 minutes to firm up and then took them out of the molds to continue drying over night.
After two batches, one with double the amount of food coloring, we wondered if a natural castile soap would also work. The bath crayons looked similar when made with the castile soap, but for some reason they didn't leave much of a mark behind on the shower walls.
We were inspired to make these from the book, Earthways: Simple Environmental Activities for Young Children, but mostly improvised the actual construction of them.
After watching Bill Nye, the Science Guy's episodes about Bones & Muscles and Blood & Circulation, Camille and Sylvia paid close attention to their pulse rate after resting and after exercising and were surprised at how much quicker their pulse rates were after activity.
We've also been watching a documentary about pandas and playing Zoo Tycoon on the computer. Sylvia has been enjoying having Caddie Woodlawn read aloud to her, and Camille has been listening to George's Secret Key to the Universe by Stephen and Lucy Hawking on audio book. It is a very engaging story with fascinating science facts mixed in. Camille and I glanced at each other with our jaws open in surprise several times while driving in the car and listening to this book. We also giggled over some of the character's antics.
Let's see, what else? Legos and Pirates 101 and Skip to My Lou, oh my! Throw in a visit to the library, our favorite Whitaker's Farm Fresh Market store for locally grown and produced foods, and two play rehearsals, and I'd call that a very satisfying two days.
