In which we get pizza from Chicago and therefore do science

Does that even make sense?

Let me explain. My Dad had a box of deep dish pizzas and cheesecake from Chicago delivered to us. (OMG! So delicious! Thank you, Dad!) 

The food came packed in a styrofoam cooler in a box. Inside the cooler, along with the food, was a nice big bag of dry ice. 

 We can't resist doing science experiments any time we find ourselves in possession of dry ice. It's what former science center employees and homeschoolers do. 

Because Dry Ice. 

Because Science.

When I rewatched these videos, I found several places where my brain was working faster than my mouth could and I said the wrong thing.  That happens to me.  Anyone else?
