We did a little experiment recently with dry ice (solid carbon dioxide). You may be familiar with it from science class in high school…or if you’re like me: from Halloween decor! Ha!
By the end of our lesson, the girls could explain to us the process of sublimation and they knew a little more about solid carbon dioxide. Mr. M majored in Chemistry in undergrad, so this was ALL KINDS of fun for him. Haha.
Mostly, though, the girls just had a blast checking out the dry ice and watching it sublimate (turn from a solid directly to a gas). 😉
ALL we did was put the dry ice into cups of water and watch what happened! Does it get any easier than that?!!!
I was all: Don’t Touch That!
And Mr. M was like: They’re fine!
We got this dry ice from a place near us that only sells it in 15 pound blocks or higher – so we had a big cooler full of it. We had fun for days…
I remember when I was little, my dad brought home dry ice once, too (he was a scientist before he became a pastor). It was so fun play with dry ice back when I was a kid – some things never change!
You can see that Paprika eventually got more comfortable around it:
And then she used it to chase me around the house!
Baby Violet loved her little science lesson. I don’t think she quite knew what to think at first…
But, of course, she HAD to inspect it…
And then she loved it!
Please note: If you do this experiment with children – please make sure you don’t let anybody touch the dry ice directly with their bare hands. It can burn you – ouch! And don’t store the dry ice in an enclosed container because it can explode under pressure…and that would be no bueno!
