I remember that I used to have this RC car in my childhood. I always wondered how it ran - so I took it apart and when I knew how it worked (with the DC motor), I tore away the motor from the car. Subsequently, I taped the motor to the top of the car along with batteries, made a makeshift propeller with scrap pieces of aluminium from my backyard, expecting the car to fly, if uncontrollably. But it didn't - the car was heavy. I was left with a broken car and a lesson on concepts of force and lift. The other lesson I learnt from this experience was that just because it seems that something should work does not mean that it will; in fact it rarely ever does. | I remember that I used to have this RC car in my childhood.
