OMSI!

A few weeks ago, a friend from Xiao Yu's preschool invited him to a birthday party at OMSI, which is the science and tech museum in Portland.  All the kids were allowed to come along and so off we went!

There was a section where you could use big blocks made out of foam to build one of those arches the Romans used to build bridges.

So the kids started stacking them up.

And then we did it!

Then it was time for the fun part--knocking it down!

There was a smaller version, which was also fun to build.  First you build the base.

And then you stack blocks on top.

And then when you remove the base, if you've done it right, it stays up.

In another section, we saw some space-related things.

Xiao Yu went inside the space capsule.

And there was a 'brain fair' going on, with all these booths set up talking about different aspects of the brain.  They even had preserved human brains that the kids were allowed to touch.  The kids touched the brain of a left hemisphere, from a woman who donated her brain to science.

And then we had pizza for lunch, cake, and opened presents!  It was a fun day!
