Super Cooled Liquid
I had read about it, but today I saw it first hand. We had below zero temperatures last night. I had left a glass with a little Sprite in my car. This morning, when I went to start the car, the Sprite was still liquid. As soon as I shook it the slightest bit, just by picking it up and marveling at the fact actually, it froze solid.

Remember this moment because it will make a great idea for the never-ending science projects you will be doing with your daughter. The best ideas are aways the simple things that actually teach a basic scientific concept.
The best ideas are always, not aways. My "l" is sticking.
We're doing a live volcano as soon as we can sit outside. I'm toying whether we should go with the good old fashioned baking soda or Coke and Mentos.
A classic! Well done. I've never heard of using Mentos but I'd go with that. In fact, I'd get lots of extras so you can enjoy a companionable snack while you watch the volcano erupt. Do the different colors/flavors make a difference or do they all work the same?
By the way, this is off-topic here and involves the Patterico discussion about Joe Horn: Sometimes it's fun to play with cats.
Oh, I get the supercooled liquid problem all the time. A case of Mountain Dew® will be brought home, but it won't be cold. So a couple of cans are put in the freezer, with the timer on the microwave set for 66:66¹, which produced perfectly chilled cans of Dew. But, if'n I forget about it and am too far from the nuclear machine to hear the alarm (and I have some hearing loss anyway), and the cans stay in the freezer too long, when opened, the soda inside turns from liquid to slush in about a second.
And what are you doing letting it get below 0º F anyway?
