DRAGSTER

   Today’s class, we made car fly.  After last week, students have better understanding of group works and they successfully finished their project.  It has four gears but each two of them are separated.  When the gears connect, the car is lifted and it starts to build up momentum.  When the gears disconnect, car flies away due to those momentum.  Other than our project, we had a pre-halloween Q&A contest about Superheros from DC universe and Marvel universe.  They all got their KitKat as reward.
