Hey guys! In this post, I'll be experimenting a bit more with my race car, and I'll be talking about the fastest cars in the world!
CAR EXPERIMENTS
~~~~~~~~~~~~~~~~~~
Many things can be tinkered with, even cars! There were four experiments, the trick, grip, power, and strength experiment.
I started with tricks. It involved the large wheels, small wheels, and the axle attachment. When I put the parts on, I just had to turn the axle around 3-4 times. The car was moving fast enough to do a wheelie.

If you are wondering how it did that, the answer is Torque. Torque means "Moment of Force." When I added the axle attachment, the car accelerated faster, that gave it a lot of torque. The more torque you have, the more it accelerates. It went so fast, it did a wheelie!
The grip experiment was a weird one. I just needed wax paper, tape, and a measuring tape. First, I measured the wax paper so it could fit on the large wheels. Then I taped them together to put them on the wheels.
The Tinker-zine said my car wouldn't move. However, my car went further with the wax paper. It had to do with Friction. Friction is a force of motion. It kept my car moving on the road. With the grip strips, there was a lot of friction. When I added the wax paper, there was less friction.
For the power experiment, I only needed my race car and a measuring tape. To start, I turned the rubber band 2 times, and wrote down how far it went. I repeated the steps, but I turned the rubber band 4 times for the second try, and 8 times for the third. For the first try, the car went 22.5 inches. The second, 7ft and 1 inch. For the third, it went as far as the tape could go, up to 25 ft!
How come it moves more when you turn the band more?The more you turn the rubber band, the tighter it gets. That caused the car to go faster when it got released.
The strength challenge was really short. To do this experiment, I needed some batteries, a fruit roll-up box, thread, scissors, and of course, my race car. I needed to make a sled for the batteries to fit in, so I got the box, and cut it into a sled shape. To drag it behind the car, I got some thread, and poked a hole in the bottom of the sled, and tied the thread to it. Then I tied the other end in one of the slits to attach the sled. For the experiment, I turned the rubber band 1.5 times around the axle. The experiment started out with the sled being empty, the car went 3 ft, 3 inches. I added a AA battery to it, the car went 2 ft, 4.5 inches. When I added a AAA battery, the car only went 1 ft, 2.75 inches. Finally, with one AA and two AAA batteries, it went 1 ft, 2 in.
I tried to add more batteries, but it couldn't move! Race cars have to be made out of light materials like aluminum so they can move fast. If they were heavy, they would move really slow!

FASTEST CARS EVER!!!!
~~~~~~~~~~~~~~~~~~~~~~
These cars can travel at amazing speeds, each one better than the last, all made by the same guy! His name was Richard Noble. The first car he made was the Thrust 1, but he sold it for parts to make the Thrust 2. It can travel up to 633 mph.
That record would've been great to keep! But he wanted to create something faster, the Thrust SSC. (Super Sonic Car) He broke his own record with the Thrust SSC going 763 mph. The car actually produced a sonic boom!
Richard is still planning to go faster, he and his team are making the Bloodhound SSC. It's still a work in progress, but they plan to make it go 1000 mph!! That would be cool right? There are many people trying to break this record, but I bet that Richard is going to beat it first.
