SCUBA diving is becoming a worldwide phenomenon with 25 million diving certifications given by PADI, the biggest dive certifier, alone. This recreational or professional activity has become possible because...

After the setback with the last car, we decided to start anew. We drew up the latest design that should prevent the car from flipping. We widened the car, which will lower the center of gravity, making...

Today we finally set off the rocket car! The day started with us walking out to a tennis court and setting up a guide line. Our guide line was about 100 feet long. Next, we started setting up the rocket...

Today we worked on the launch controller. The launch controller is important because it is the only safe way to set of the model rocket engines. We made the wires about ten feet long to protect us from...

Today we managed to put the wheels on the rocket car! To do this, we started by finding a drill bit to make a hole for the wheel nails. After measuring the wheel nails, we decided to use a 1/16" inch...

Today we worked on cutting out the sides of the car, or the top view. We tried to make the head of the car like the shape of a bullet. This will hopefully help the aerodynamics of the car. Since we were...

Today we cut the top of the car with the band saw. This was exciting, as we got to see our car slowly take shape. We tried to make straight cuts toward the outside of our marked lines and keep all of...

Today we completed our final design for the side view of the rocket car! This design is meant to be aerodynamic and easy to cut in the band saw. We also want to leave enough material on the car so that...

Space elevators could be the next big innovation in space travel. They would revolutionize how we sent payloads into space, by dramatically reducing the cost and conserving energy. New experiments on...
