Soap Experiment

Pictures, explanation and experiment by N and R. Edited by truly yours. Here you go:

We did a little soap experiment today about "which soap floats and which sink". We used three different brands of soap. Irish spring, Ivory, and Dial. Here is what we came up with:


 As soon as we put a bar of Dial in a container with warm water, it sank immediately.

 Irish spring:

Next, we decided to put a bar of Irish spring and that sank too.


Last but not least, we put a bar of Ivory.. Hey! Ivory floats! Woohoo!

Since ivory is the only one that floats, we decided to do some research why that floats alone. We found out that the mixing process used in making Ivory soap adds air into the bar which reduces its density and thus make it less dense than water. Guess what that means.. you will never loose your bar of soap in your bubble bath when it slips off your hands..

Since we were at it, we decided to take it a notch up and did one more science experiment. We microwaved the bar of ivory on a  piece of waxed paper for about 90 seconds. Here is how it turned out:



Huge different, right? We have some Soap Mousse!!

The soap felt brittle and flaky, but its still soap! It is just a huge chunk of soap now! And definitely a conversation piece as it now sits in the guest bathroom! 

Researching why the soap turned into foam, we learnt this: Soap softens when heated. The air and water trapped in the soap is also heated which causes the water to vaporize and the air to expand. The expanding gases pushes on to the softened soap causing it to expand as well and become foam-like. Popping popcorn works pretty much in the same way. We have some cool plans for this Soap Mousse. Stay tuned!! More experiments coming later in the week!

Have you been wondering like myself...

Every now and then for the past month or so, I have been getting emails with blog posts and recaps from Nara-saz and I have absolutely NOTHING to do with it. I have not been here to make any changes to the settings nor have I have given admin access to anyone else. So it boils down to this one thing, Nara-Saz is missing me and calling me and hinting at me to pay attention and give it some TLC. So I am calling out to all my readers to please go ahead and open up a notepad and start to write/draw something interesting... Submit it to me and your post will be on Nara-Saz... How does that sound??

In the meanwhile, I wanted to wish everyone a Happy Eid Mubarak. Hope everyone had as much fun as we did. The kids decided to celebrate Eid in a grand way this time since Eid was during the summer break and they had the time to prepare and not worry about school.

Have you heard that a picture is worth a thousand words? I will conclude with these picture.. Great job RUNRSZ!!!
