To do the trick, first put a unwrapped bar of Ivory soap on a paper plate or piece of paper towel.
Place the soap in your microwave for about 90 seconds and it will puff out and grow into this amazing looking foam sculpture!!!! I didn't let my daughter watch the whole time because of the microwaves harmful rays! Interesting Information: My Father, who worked with radiation, has told me the most dangerous place to stand is the side of the microwave because that is where the harmful rays leak out! He said the front has a protective shield on it so I just thought I would pass that along since I am mentioning the dangers of microwaves.
Now you can see how the soap puffed out! My daughter absolutely LOVED this! We've done it three times and she keeps asking about doing it again! I explained to my daughter that the reason it puffs out is because there is air inside the soap that makes it expand when heated ... she seemed to understand! To make our Ivory Soap Puffed Sculpture more beautiful, I let her put drops of Liquid Watercolor (you could use food coloring) on it to paint it! Be careful because the soap is hot right out of the oven and especially in the center of the soap!
The sculpture is not at all permanent and flakes apart so it is definitely an "in the moment" activity! My daughter loved touching the sculpture and wanted to save pieces of it!!!
Here is a finished "Colorful Ivory Soap Sculpture" again! Beautiful! (or Not?) What do you think? We put the finished sculpture back in the microwave to see what would happen and there was not much difference. I appreciated that my daughter wanted to keep experimenting!
