It’s quick and easy, and all it will cost you is the price of a bar of Ivory soap.
For your convenience, I’m including an Amazon Affiliates link in this post:
You have to use Ivory because of the amount of air that it contains. You can get the scientific explanation here.
We started by passing the bar of soap around so the Hooligans could touch it, smell it, and see how light in weight it is. You could also cut the bar in half to have a look at how “airy” it is inside compared to other, more dense bars of soap.
Place your Ivory on a microwave-safe plate, and nuke it on high for a minute or two, and watch the amazing transformation that takes place. How cool is this?!
Be careful! It might be hot (ours was not after 1 minute).
Now, normally at this point, we would crumble this monster up, and use it to make a batch of our homemade laundry detergent, but not today!
