A while back, I posted a couple of pictures of a moustrap car that Katie built for Science Olympiad.  Quite a few people have looked at those pictures while searching for “Reversible Moustrap Cars”.  That prompted us to make a short video of how we made our moustrap car reverse.  Click on the video below to see how we did it.  Enjoy!  By the way, this video was made with the great Openshot Video Editor for Ubuntu Linux.

Katie and Ana participated in the Science Olympiad at their schools before Christmas.  They both went to Bozeman, MT for the state finals.  Ana studied birds, and Katie made a mouse trap car.  Here are a couple of photos of the mouse trap car.  It had to go forward a certain distance, stop, and reverse the same distance, without any human intervention.  It took a lot of brain power trying to figure out how to make it all work, but we did it!  Good job Ana and Katie on your projects.  Click on the pictures to see larger views.

(UPDATE 3/17/10 – Due to the large response on searching for “Reversible Moustrap Cars”, I made a “How To” video showing how we made our Mousetrap Car reversible.   Check it out by clicking HERE. )
