    we’re going to have to try this, wow!

    neat! Tell me tho, does this just work with Ivory soap? Ivory stings our skin so we can’t use it.

    I have to do this with Noah!!!

    I am so happy I found your blog. This is so going onto the list of things to do (when she’s older). :)

    Love the soap balls, if ivory soap didn’t dry my skin out on contact I’d be making these today just for kicks.

    I especially enjoy how it’s more than 1 poject for the same item. How interesting about how ivory soap was invented. I love these accidental finds.

    I love this whole entry! What a wonderful way to spend some time. I did want to let you know however, that there is a typo in your little booklet. They are “Unifix” cubes, with an “i” not an “e.”
    Thanks for sharing with us!

    This is very cool. I don’t suppose you can do this without a microwave? We live in the dark ages.

    I am amazed by the research, care, and detail which went into this series of activities. My scientific little boy would love to do this. love, Beth

    Totally making my list of rainy-day activities.

    This is so cool!!! We don’t have a microwave but I ‘ll bet Nana will let us use hers :)

    I really like the idea of the lavender/ivory soap balls.

  17. gracie

    it’s because of the water in the ivery soap that i buy it months before i need it, take the wrapper off, and let it ‘dry’ out making it last longer

    this experiment looks like fun! so i’ll buy some ‘new’ soap and try it with my young ones

    thank you

    Wow. Who knew that craft soap could be so easy?

    I bet it smelled wonderful. :)

    What a great idea. I have some science loving kids who’d like to do this. I think I’ll save it for their next day off from school.
