I took the train to Minnesota over spring break. One of our excursions was to visit the Minnesota Museum of Science, a place to spend quality time with kids and science. One of the museum's trademarks is a set of stairs that dings musical notes when walked upon. The video part is lousy quality, but the audio is fine.
When we came home, the kids made a model of King Tut's tomb out of a little figure of King Tut (he's in the box inside a box inside a tomb) and assorted goods found on any active dining room table such as fool's gold, boxes, assorted stones, erasers, etc..
