For the last month or so Jackson has been working on a Knex roller coaster. Doug has helped him some of the time, but Jackson has been working very hard to finish it. Saturday, they finished it! Jackson was so excited. It is pretty awesome:
There's a motor (or a manual crank) that carries a ball to go through all the different parts of it.

Very cool...way to go Jack! It was fun playing with it even when it was only partially finished; I'll have to come back and play now that it is finished!
