  • Carly Young

    Ivory soap and a microwave this site has fun stuff for the kidlets

  • Colleen Gallinger

    With just a small square of "Ivory Bar Soap" you can create an "Ivory Soap Explosion!" Great sensory experience.

Science behind Ivory Soap in the Microwave { this almost makes me wish we had a microwave}

This is what happens when you microwave a bar of Ivory soap! Then you can tear it up, color it, and mold it into shapes! It's not wet and messy, either! This is awesome!

Fluffy Bath Paint, using the microwaved ivory soap bar (see fun stuff for the kiddos)

Pinner said - Place a bar of Ivory soap in the microwave for two minutes to make a soap cloud. We then turned it into bathtub paint. The kids loved it! (I was probably just as entertained.)

Gak/slime/flubber... a recipe for making the fun, stretchy, slimy stuff. Note: Contains Borax.

  • Sally Parsons

    In Australia, like many other countries, Borax is classified as a poison - does anyone know of an alternative for its use in recipes such as this?

  • Kaleen Kizziar

    Didn't work. Just made clumps

  • Kelly Gregg

    Use liquid starch if you don't have borax. Also, make sure you add the 1/2 c water in with the bottle of glue. If you don't it comes out rubbery and breaks apart.

Science Experiments the kids will like.

    "Science Bob" was my elementary school science teacher nearly 2 decades ago! I saw him on Jimmy Kimmel recently and was stunned that he hasn't changed a bit. He's a nice, cool, smart guy.

  • Megan Mills

    That is so stupid.

  • Melissa McClanahan

    Always a critic in every crowd.... This looks best for younger kids

  • Melissa

    Wow. I was expecting a better ending to this experiment.

Ivory soap - You may recall that Ivory soap floats in water. The reason for that is that unlike other soap, it has a a bunch of air whipped into it. This is important because when you microwave it, all those tiny air bubbles expand and make your soap look like this

  • Clay & Cloth

    I just love this kids face.

  • Gloria Harris

    yep. it also smells so strongly that it gave me a headache.

  • Pam McKenna

    I think I'll try this, but will try a smaller piece first.

  • Matthew Villani

    For me the Ivory smelled pretty mild, especially compared to other soaps I tried like Irish Spring, Coast, and Dial (although Dial made an Ivory-like soap cloud)

So simple and so fun... - The Meta Picture CAN"T WAIT TO HAVE GRAND KIDS THIS OLD!!!

    I tried this once and the soap just melted into a brown goo.
