Science at Home

By -
Charlie and I started a fun science project to make a bouncing egg by soaking an egg in vinegar.
On day one we noted how the egg sank and the calcium carbonate in the shell reacted with the vinegar causing bubbling on the shell. 

On day two the egg was larger and it was floating!

Day three the shell had dissolved and the egg was looking larger.

The instructions said to let it soak for up to 10 days. On day 5, Charlie got eager (and bored) and decided to bounce the egg while I was on a conference call. The egg burst like a water balloon full of vinegar! The science lesson turned into a cleaning lesson at that point!

I was sort of sorry we didn't get it see it through and see if the egg might have been bouncy. Maybe we will try again...

Frozen Party Details

Like most girls her age, Sarah Graves LOVES Frozen and has known for quite some time that she wanted a Frozen birthday party. I was so excited when I saw this invitation on Etsy and she loved it too! It reminded me of an infographic. The Frozen theme was a lot of fun! There were so many things to choose from that I took to pinterest and eventually decided on the ideas that I would use for this party. I found this great Arendelle banner here on Pinterest I was so grateful that my sister did a snowflake Christmas and had tons of snowflake ornaments to hang as decorations! This party theme was a lot of fun to plan the food. Kristoff's ice cubes were made from Jell-o with an ombre effect. I found the recipe here on Pinterest. I doubled the recipe to make a 13x9 size pan of it and I made 2 13x9 pans of it. The made plenty of "ice cubes" to fill 35 cups. They turned out really cute! My parents made this Elsa cake and did a fabulous job

Cloth vs. Disposable

By -
We have mostly been planning to do disposable diapers because I felt that cloth would just be too much work when I go back to work.  Then, we saw these diapers called happy heiny's ( www.happyheinys.com ).  These looked much different than what I envisioned cloth diapers to look like.  Mom used cloth diapers with me and Jeanne', so she felt totally up for using them while Sarah Graves is at her house.  I started looking into the cost comparison and depending on what type of cloth diapers you buy, you can save anywhere from $1200 - $1700.  That is pretty attractive, not to mention knowing that you aren't filling up a landfill somewhere.  There are lots of different varieties of cloth diapers out there, but the ones that seem to be a good investment and user friendly are diapers that have snap closures, with a pocket for an insert to absorb the contents, and they are one size that adjusts as your baby grows from a newborn up to 35 pounds.  You can also purchase the traditio
