As the start of the school year is just four days away (have I mentioned that I'm not excited about Aiden being gone all day?), we've been trying to cram in as much fun time as humanly possible. Rose Garden, Arboretum, Washington Park, Children's Museum, lots of other parks, library, board games, visiting friends, art projects....whew! And of course, lots of science experiments.
We woke up today and I realized that I was plumb out of ideas. We didn't really want to go to the park again and just sitting outside doing sidewalk chalk sounded kind of boring, so after a visit with a friend who is moving to Arizona, we jumped into some brand new science experiments.
First one up: Ivory soap in the microwave.
Yep, that's it. (Take it out of the plastic wrap first. That was there just for pictures sake.) Set an unwrapped bar of Ivory soap on a plate and stick in the microwave for 2 minutes. Want to see what happens? Watch the video below. It will look like it's going to be hard to see into the microwave at first, but you'll be able to see, trust me! (Note: There is no audio. I was using our point and shoot camera instead of the video camera, and the point and shoot doesn't capture audio).
For those of you who couldn't/didn't watch the video, the soap turns into foam. Here are the boys poking at it.
Tips for parents if you want to try this:
1. Yes, it does need to be Ivory brand soap. Other brands of soap will just melt.
2. It will smell like soap in your house for hours. Strongly. Ivory is slightly perfumed and microwaving it enhances that, so if you're sensitive to perfume-y scents like I am, make sure you have windows open and possibly a candle lit. The candle I have broke through the scent a bit for me and made it easier to handle. I still ended up with a slight headache, but it was worth it for the experience for the boys.
3. Let it cool before the kids touch it! It's hot.
4. It will make a mess if you let the kids play with it (which you should totally do - the stuff feels awesome). It turns into soap dust and will probably need to be vacuumed up. We took a large chunk and let the boys dissolve it in the bathtub later that night. Hey, they got clean.
The second experiment of the day was done with John's help. This time we took five simple ingredients: Strawberries, water, liquid soap, meat tenderizer enzyme, and rubbing alcohol. Can you guess what our experiment was?
DNA extraction!
The fuzzy stuff in the middle between the berry puree and the alcohol is the strawberry DNA.
This was a super fun experiment and while it required a little bit of time and work, it was fun to play with DNA (I don't get to say that often enough, methinks). We even took some of the DNA out by using the end of matchsticks and rubbed it in between our fingers. It felt like boogers. Also, my kitchen smells strongly of alcohol. Between that and the soap, it's a fairly clean smelling kitchen!
So that's what we've been doing. We'll try to make the most of our last four days of summer before Aiden heads to 1st grade and Nathan begins another year of preschool.
