Scary spiders, liquid nitrogen, etc.

Went into Sam's classroom to do a liquid nitrogen demo a week ago last Friday. The kids loved it. And the welding supply place where I get it gave me MUCH more than the 8 liters I asked for. (They don't really measure it--they just guess, tapping on the side of the Dewar as they fill it up.) Frozen all sorts of things for the kids, and I think they actually learned the few basic things you can impart with lN2.

A kind woman at church gave Sam a remote-controlled tarantula. How cool is that?

I think this picture needs no caption. Yet, here I am, writing one.

This is just the sort of activity that makes Saturday mornings fly by.

Saturday, after the nap, we went to the Play Museum. This time we went into the butterfly garden. Josh is old enough not to endanger the animals. In fact, we was nervous about the butterflies, who happily meandered about at Josh-eye-level.

Sam was not nervous about the butterflies.

This is an Indian Dead Leaf butterfly. If it opens you can see the interior of its wings is a bright, gorgeous pattern.

At the PM Sam and I went off to their video-game and pinball exhibit.

 

 

Here's Sam playing one of the two pieces he wrote a couple of weeks ago. He'll play one of them a week from Wednesday at an evening talent show at work.

 

 

There will be a big presentation a week from Friday at Montessori. Josh's class, the Crabapple Room class, will perform this piece. :-)
