Does your soap float? Mine doesn’t. The stuff I make, I mean. Growing up though, all Mom bought was Ivory, which is famous for its floating, and I spent plenty of time zooming it around the bathtub like a boat.
The secret to floating soap is simple, even for those of us with science-challenged brains. Whip enough air into the bar of soap so that its density is less than water, and – it floats!
Ivory tells their story of discovering floating soap this way: an employee left on their lunch break, and forgot to turn off the mixer, which added extra air bubbles to the vat. Nothing was thought of it until phone calls started coming in, asking for the soap that floats!
According to this article, that may not be exactly the way it happened, but I’ll leave that to you to decide. Either way, I’d recommend checking out this newspaper article from 1979. It’s pretty cool!
So now what’s left for me to do but to try to make floating soap myself?? Stay tuned!!
P.S. I saw this super cool Ivory soap box at my husband's grandmother's house this weekend. What perfect timing for this blog post!
