How Sublime - January 26, 2006

I'm doing a little archiving today - that is printing out my blogs and putting them in a binder so that someday, someone might find them and say "that was one crazy weird woman". I thought it might be fun to spend a little time sharing my favorite blogs, or ones which seemed to generate the most interest by readers. This one was just too much fun. (Disclaimer: do NOT try this at home. It is dangerous! And fun! But don't do it.)

How Sublime - January 26, 2006

Today, we received a gift in the mail from Omaha Steaks. Now, you might think that the gift was meat, and certainly, there was some in the package. But the real gift was a bag full of dry ice. We were headed to the library, but I recognized the fleeting opportunity for a fun science experiment. So, I took it upstairs and cautioned everyone not to touch it! That was instant permission to squeal. We put some in water:

We talked about CO2, how the solid sublimes directly into gas, whether hot or cold water was more effective. Then, we put out a flame with the gas. What else could we do? Well, we filled up some baggies and watched them pop. After the first squeal or two, that just wasn't enough bang, you know? So we tried something more: (note for you safety geeks, we were behind a protective door)

So much fun. Life is like that you know? You have to catch those moments when you can.

We watched it 5 times in a row. Aidan wanted to know if there was any more?! The other three just watched and laughed and laughed. I am glad that you posted it again. That was a good one!
