2-4-6-8...Let's Sublimate!

Chris and I justify our Omaha Steaks purchases by agreeing that we would otherwise be unable to provide the kids with such fine, interactive lessons in sublimation :

You have me baffled. Do you mean sublimation as in chemistry class or as in Freud?

Right, send the boys round. I have tons of dishes here that need to be done, clean ones, and dirty ones - LOL

Sublimation as in chemistry - the change from solid to gas without passing through the liquid state. Dry ice (helpfully supplied in quantity around our steaks) sublimates very dramatically! It's also a great way to show how some gasses are heavier than other gasses - the CO2 gas in the sink doesn't float up because the regular air above it is heavier. The only complication (but also something to learn) is that the regular air is much warmer than the CO2 gas - you can feel the temp difference with your hand. If I had a way to get warmer air into the bottom of the sink, we could show the warmer air rising. I tried adding warm water to the other sink, hoping that warm air would back up through the connected drain, but it didn't work.

I think applying Freud's sublimation theory to meat and/or dry ice - particularly with young boys as the investigators - might not be viewed kindly by authorities...

But you could hope that they sublimate their desire for your steak into a desire to wash dishes?
