Today I went to a Lego work shop led by the Lego man.
The challenge was to get the fastest car, so when I started I teamed up with Vince and Theo. We experimented with different gears and how if it was big to small it would go fast, and if it was small to big it is slow.
After the car was constructed we did time laps over 5m. The first car did it in 4 seconds,it was good that we got a time like this at first.Then we rebuilt it with more gears and it did it even quicker. My fastest car did it in 1.9 seconds, which we worked out to be about 5mph.
The slowest car took 1:45 seconds to do 1m.
