I saw a die cast car in a mini clear plastic box with straws fitted on each end with a leaf blower behind the straws. They placed the ballast more towards the front and then more towards the rear. They had the pivot point in the middle of the car and turned on the leaf blower. As soon as the air entered the one end of the mini tunnel, the car would lift up at a certain point. No matter where the ballast was placed that car raised up and pointed in the direction where the ballast was located. It basically showed how a car is like a dart that even when the dart is thrown backwards it turns forward to hit the dart board with the point because the weight is up front...... Anybody know where this video is located on youtube, please let me know, thanks!
