My Dad and I are having a competition on who can make the fastest car out of my knex and rubber bands. So far we have made about eight changes and modifications to our cars.
We have changed the wheel size, the rubber band length, the length of the car, gears and rubber bands systems. We race them to see who's is faster after we make changes. Then we both work on the cars and make new changes - take away or exchange or put on new parts.
My Dad made another car powered by catapault power and it is like an automatic attacking machine when you wind it up because the catapault is pulled back and then it flings forward and then smashes everything in its way. We have made our own power system using cogs and rubber bands.
My Dad ordered new pieces for our cars because we were running out of pieces that we could put on our cars. The parts that have come today are different to what we have been working with so far so hopefully they will make our cars faster.<
