This week's agenda - roller coasters and more robots. I thought I'd be clever (and cheap) and use those foam swimming "noodles" as roller coaster tracks. When you split them in half, you get two tracks with a trough the perfect size for a marble. But cutting those tubes in half is not as simple as it looks, especially when you've only got those kids'-sized, round-nose safety scissors to cut with.
The robot kids learned to run their robots across a rope just like cable cars do in the Swiss Alps. Actually our theme is rescuing hikers (Lego mini-figs) in the Himalayas. In this exercise, the robots had to travel across a rope and drop a "care package" into a can on the other side of the table (the can was supposed to represent the hikers trapped inside a cave). It's been fun to see how creative the kids can get, but their unquenchable energy is wearing me out.
