Scientific

Density is exhilarating. If anyone wants this recipe, email me.

Eggs can be suspended between salt water and tap water.

 
Jane had a nasty loose tooth just hanging from her gums for a few days. She could poke it out and make this face. It finally fell out and the tooth fairy took two days to remember to come. The first day was the Sabbath though so we figured she doesn't work that day... it was worth the wait because she brought a chinese skipping rope which turned out to be hours of fun for all of us.

We are happy to know that this new little neighborhood is full of kids the same age as ours. The last few days have been spent like this. All 3 of our yards back onto each other so its a perfect gathering place for the kids.

The new fairy houses in our new trees have begun. Jane is taking her time to find the perfect spot but the boys have already started.



This is the beginning of Charlie's. 

This was way entertaining. Plus the whole house smelled Ivory clean.

Here is the Ivory soap. It just grew and grew. I couldn't believe it.

This is the Dove soap. It didn't fluff up like a marshmallow, it just sort of melted.
Everyone should try this out. The info is below.

Ivory Soap Souffle - Microwave Trick
Blow up a bar of Ivory soap in the microwave.

The microwave oven is not just for warming leftovers. Grab a bar of fresh Ivory soap and gather your friends around the microwave oven. Sure, you could do it at your home, but save this great trick for the break room or the staff cafeteria. In under two minutes, you'll have the best soap soufflé you've ever seen.
Walk down the detergent aisle and you'll see dozens of different kinds of soap. Green soap, smelly soap, big soap, even soap that floats. Ivory soap is famous for floating. How do they make some bars of soap float and others sink? Believe it or not, we're going to cook the soap in the microwave oven to uncover the secret.
Materials
  • Bar of Ivory soap
  • Various bars of another brand of soap
  • Deep bowl of water (or a plastic tub)
  • Paper towel
  • Microwave oven

This experiment requires adult supervision and permission to use the microwave oven. 
Adult Warning! You will not be able to sneak co-workers into the cafeteria to see the incredible expanding soap trick without filling the office with the lovely smell of Ivory soap. Besides, the chorus of ooohs & ahhhs erupting from the cafeteria is a dead giveaway.
  1. Fill the bowl with water.
  2. Drop the bars of soap in the bowl of water. Notice how all of the bars of soap sink except for the Ivory brand soap. Why?
  3. Remove the Ivory soap from the water and break it in half to see if there are any pockets of air hiding in the middle of the bar. If there are, that would make the soap float, right? But there are no pockets of air. Hmm...
  4. Place the bar of Ivory soap in the middle of a piece of paper towel and place the whole thing in the center of the microwave oven.
  5. Cook the bar of soap on HIGH for 2 minutes. Don't take your eyes off the bar of soap as it begins to expand and erupt into beautiful puffy clouds. Be careful not to overcook your soap souffle.
  6. Allow the soap to cool for a minute or so before touching it. Amazing... it's puffy but rigid. Don't waste the soap. Take it into the shower or bath. It's still great soap with a slightly different shape and size.
What would happen if you microwaved a marshmallow? Try it! Put the marshmallow on a plate and microwave it for about 30 seconds. What happens? 
How does it work?
Ivory soap is one of the few brands of bar soap that floats in water. But when you break the bar of soap into several pieces, there are no large pockets of air inside. If it floats in water and has no pockets of air, it must mean that the soap itself is less dense than water.  Ivory soap floats because it has air pumped into it during the manufacturing process.
The air-filled soap was actually discovered by accident in 1890 by an employee at Procter and Gamble. While mixing up a batch of soap, the employee forgot to turn off his mixing machine before taking his lunch break. This caused so much air to be whipped into the soap that the bars floated in water. The response by the public was so favorable that Procter and Gamble continued to whip air into the soap and capitalized on the mistake by marketing their new creation as "The Soap that Floats!"
Why does the soap expand in the microwave?
This is actually very similar to what happens when popcorn pops or when you try to microwave a marshmallow. Those air bubbles in the soap (or the popcorn kernels or the marshmallow) contain water. Water is also caught up in the matrix of the soap itself. The expanding effect is caused when the water is heated by the microwave. The water vaporizes, forming bubbles, and the heat causes trapped air to expand. Likewise, the heat causes the soap itself to soften and become pliable.
This effect is actually a demonstration of Charles' Law. Charles' Law states that as the temperature of a gas increases, so does its volume. When the soap is heated, the molecules of air in the soap move quickly, causing them to move far away from each other. This causes the soap to puff up and expand to an enormous size. Other brands of soap without whipped air tend to heat up and melt in the microwave.
