This science project requires the Magic Bullet Train kit, available for purchase from the Science Buddies Store.
When working with magnets, keep them away from your mouth, and away from small children and pets. While trains that fly through the air might still be science fiction, trains that float just above the tracks without actually touching them are real and are actually used in a few countries today.
Have you ever seen a science fiction movie or show where vehicles hover just above the ground without touching it?
Hovering is also referred to as "levitation," so making an object hover above the ground using magnets is called magnetic levitation, or maglev for short.
A diagram of the maglev train model you will build in this science project (left) next to a picture of the actual model train (right). The train, however, cannot carry an unlimited amount of weight; the magnets can only supply a limited amount of force depending on how strong they are. Follow the instructions that came with your Magic Bullet Train kit to assemble the train with the help of an adult.
If you are using sandpaper to make your wooden block into a train shape, be sure to leave a flat surface in the middle on top of the train; you will need a place on which to put the plastic cup later. Watch this instructional video from Dowling Magnets on how to assemble your Magic Bullet Train kit.
As you gradually add water to your plastic cup, your maglev train will sink closer to the tracks.
If your plastic cup is completely full and the train is still not touching the track, either add a second cup, or start over using a larger cup.
If you do not have a kitchen scale, pour the water from the plastic cup into the glass measuring cup and measure its volume in milliliters (mL).
If you have a kitchen scale, take the plastic cup off the train (do not pour the water out!) and use it to measure the mass of the plastic cup, including the water.
Repeat steps 2–7 four more times, starting with an empty plastic cup on top of the train each time. Did the same part of the train always touch the track first, or were your results different for each trial? Compared to a typical science class, please tell us how much you learned doing this project. The Ask an Expert Forum is intended to be a place where students can go to find answers to science questions that they have been unable to find using other resources. If you have purchased a kit for this project from Science Buddies, we are pleased to answer your questions. Good Question I'm trying to do Experimental Procedure step #5, "Scrape the insulation from the wire. Physicists have a big goal in mind—to understand the nature of the entire universe and everything in it! Our universe is full of matter and energy, and how that matter and energy moves and interacts in space and time is the subject of physics. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use.

Kato Interior Passenger Car LightsWhile some Kato passenger trains have factory-installed interior lights, and others make no provision for lighting, most of Kato’s trains made in the last ten years use a standardized interior lighting system.
The magnetic force can be used to make an object hover above the ground by pushing against its weight. Some high-speed trains actually use magnetic levitation, meaning they float above the track using magnets, and do not actually use wheels! The magnetic force between the tracks and the magnets on the train pushes up against the train's weight, which allows it to float above the tracks.
Eventually, if you add too much weight to the train, it will sink down and touch the tracks.


It's not as smart as you are, and it may occasionally give humorous, ridiculous, or even annoying results! If you are going to shape and decorate your train, now is the time to use your sandpaper and paint. Stop adding water as soon as any part of the train touches the track, even if it is just a corner or an edge. One milliliter of water has a mass of one gram (1g), so you can use the water's volume to figure out its mass. Also record which part of the train touches the track (corner only, edge only, entire bottom of train) Note: If you are not using a kitchen scale, your calculation will not include the mass of the plastic cup, but you can assume the water itself is much heavier than the cup, so this is okay as an approximation. Can you use these magnets to make a magnetic "brake" at the end of your track, to prevent the train from falling off (for example, if you give the train a good push, or tilt the track so it slides downhill)? The experiment simulates the compacity of people that the train can hold before rubbing aka damaging the tracks.
If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help. To reach that goal, they observe and measure natural events seen on Earth and in the universe, and then develop theories, using mathematics, to explain why those phenomena occur.
Physics teachers spend their days showing and explaining the marvels of physics, which underlies all the other science subjects, including biology, chemistry, Earth and space science. Our system will automatically choose the best carrier at the time of shipment to help us deliver the lowest prices and fastest service possible. This consists of a small lightboard, some brass strips that connect it to the wheel-mounted pickups (which are pre-installed), a strip of reflective tape and a transparent plastic diffuser. This consists of a light unit and some brass strips to connect it to pre-installed electrical pickups, a transparent plastic diffuser to spread the light evenly the length of a car, and a strip of mirrored tape that attaches to the roof of the car. In this physics science project, you will build your own levitating train model and test how much weight it can hold before it stops hovering above the tracks.
Magnets are metals that generate a magnetic field, which has two magnetic poles: north and south.
In this diagram, we have color-coded the magnets so the north poles are red and the south poles are blue. Notice how we have used red and blue to indicate the north and south poles of the magnets again (like in Figure 1), but in the actual photo on the right, the magnets just look black. In this physics science project, you will build your own maglev train model and see how much weight it can hold before sinking to the tracks. Keep in mind that your train might not stay perfectly level when it does finally touch the track; it could tilt to one side, with only one corner touching the track.
Scientists like to calculate the average of their results because small changes in each trial mean you might not get exactly the same number each time. Hint: You should use a sturdy piece of cardboard or another block of wood to form a "stop" at the end of the track, then attach one magnet to the train and one to the stop.
Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. Physicists take on the challenge of explaining events that happen on the grandest scale imaginable to those that happen at the level of the smallest atomic particles. Their work serves to develop the next generation of scientists and engineers, including all healthcare professionals. Some of the earliest models (the Passenger Car Lighting Kit, model 11-201) used a different type of electrical pickup, but for later ones (starting with the New Passenger Car Lighting Kit, model 11-204 and the six-pack set 11-206) the pickups were standardized too. Depending on which way two magnets are facing, their magnetic fields will either attract or repel each other, as shown in Figure 1. However, in real life, magnets can be many different colors (for example, if they are painted), and the north and south poles might look the same. Their theories are then applied to human-scale projects to bring people new technologies, like computers, lasers, and fusion energy. They also help all students better understand their physical world and how it works in their everyday lives, as well as how to become better citizens by understanding the process of scientific research.
When these were introduced in 2004 white LEDs were still rather expensive, so Kato provided both the 11-204 set for 400 yen, and an Interior Light Kit with White LED (model 11-209) for 700 yen that was identical except for the light unit.


To learn more about magnets, you can also read the Science Buddies Electricity, Magnetism, & Electromagnetism Tutorial. Gravity is what keeps us from floating off into space by pulling us down to the surface of Earth. In your lab notebook, make sure you record how the train touches the track; is it just one corner or edge, or does the whole bottom of the train touch the track evenly?
These were also available in six-packs at an effective price about 16% less per unit.These original kits had a lightboard separate from the white bracket that held it in place (and which needed to be assembled along with a small strip of reflector tape on the underside of the lightboard). Interestingly, gravity is different on different planets; for example, Mars has less gravity than Earth because it is smaller (which means if you were on Mars, you could jump a lot higher!). So, while an object's mass is the same on each planet, an object's weight is different on each planet.
DCC in particular provides high sustained voltages, which could lead to overheating with bulbs. The new support is 2mm taller than the old one, and tapers to a circular pin where the old one ended, with the top of the pin being flush with the top of the diffuser. This assumes I’m locating it at the far end from the lightboard and the other circuitry, where it will block the windows and one set of doors.
And capacitors fail badly when their voltage is exceeded, often with destructive results to whatever surrounds them.
But capacitors get much larger (and more expensive) as voltage increases, and I’m optimizing for N-Scale.
It's narrower, intended to fit the new Japanese subway train models they're producing, but it's also described as being brighter (as if that were needed). In late 2011, Kato announced a new lightboard for their subway train models in Japan, which is also to some extent compatible with the older models. At worst, it would provide much less run-time due to the lower typical voltages used.Space RequirementsI need to fit the circuity inside the car, which imposes some space requirements.
More critically, I also need to either fit the capacitor below the light-pipe (which means an effective height limit of around 8 mm) or place it at the far end of the car and run wires the entire distance.
In either case, some modification of the interior would needed, and my length limit was probably around 18 mm before I blocked a significant portion of the interior.
However, putting the capacitor at the far end from the lightboard, and putting the other components near the lightboard, would leave the middle of the car unblocked (except for some wires, which could be painted).So, assuming a cylindrical capacitor (the typical shape) I could fit one about 8 mm x 18 mm. That was my most significant constraint.After the initial testing, I switched to using a surface mount capacitor. Models that will fit inside an N-scale train are limited to at most several thousand microfarads, and in practical terms much less. In addition, the varying intensity as the capacitor drains and recharges may help make the flicker less obvious even when it’s too long for the capacitor to cover. Side by side comparisons of an unprotected car and the eventual 100 μF circuit showed a very large apparent difference, even when the protected circuit was fluctuating in intensity. For a Kato lightboard with R=560 Ohms, and a 100 μF capacitor, the time constant is 56 milliseconds. That said, the result is a very compact design, and the voltage should work fine for N-Scale applications unless you have a beginner’s system that is seriously overvoltaged.
The rectifier used in this circuit is rather oversized, about 20mm across and rated for 70 volts). This is an interesting circuit that replaces the resistor typically used with an LED with the LM334Z, allowing the LED to light at lower voltages. However, I suspect that this circuit has some issues with heat generation at typical LED currents, and may be unsuitable for very small spaces.Technical ReferencesAnalogic AAT4610A data sheet.
This is a current-limiting MOSFET circuit designed to control inrush current to a supercapacitor used in memory-card applications. This is a simple integrated-circuit voltage regulator, which I used for the Voltage Regulator circuit.
