Question

hi for my scince project i have to make a roller coaster. Size should be about normal.

1.Q what should I use?(materials)
2,Q What should I do?
3.Q tell me step by step please!

Answer 1

Wire Coat Hanger or small gauge wire and create a single tube roller coaster.

If you are going to make a typical steel roller coaster (or wood for that matter) then you are talking a huge, mammoth piece of construction. Clearly, no one person can do that easily, you want to make a model and the best material to work with would be something that is bendable, will hold its shape, that can stand up on its own and is cheap. Wire coat hanger fills those requirements nicely. If you can’t find enough coat hanger then go to the home supply store and look for a small gauge wire (the smaller the larger diameter), try something around 16 gauge. The idea is to have something you can bend with a pair of pliers or your hand, but it will be tough enough to hold its shape once you let go of it.

Ideally you want to make two parallel tracks, but it will be difficult to keep the spacing right. I suppose you could use wooden spacers, or you could use small pieces of wire and mechanical or plumbing solder to solder the connections together. If you use wire then you won’t have the compression resistance. If you use something like pipe cleaner then the wire is too soft. Plumber’s solder has an acid core so it will tend to melt the wire together and it is only to be used on smaller gauge wire. Electrical solder has a rosin core so it won’t melt or react with the metal. The connection won’t be as tough though.

I would start with a cardboard box, which is sealed on all sides, for your base. Old cereal boxes will work well since they have a water proof wax coating usually, if you get a big box then you can save the cereal in the bag and use the large box for your base by just cutting it into two shallow sections (or pans). Then build a set of horizontal wires to be your supports. Then you can run your wire in the pattern you want for your roller coast to take and support it with simple metal arches that are all tied into the horizontal wires in your base. When you finish then you can get Plaster of Paris and pour it into the pan to the edge of your box; this will be like pouring concrete over your horizontal wire. The horizontal wire will be like your rebar in the concrete.

If you then get a magnet you can run the magnet along the track. If your wire is not steel, but copper then you are going to have to run an electrical current through the wire to give it a magnetic field; no more than 9 volts though. This type of coaster (using only one wire) will be like one of the steel over head rails coaster. The cars will travel under the steel tube that your wire will represent. You can form loops, and all the bends you want.

A roller coaster starts out in the loading/unloading shed where the people line up to get on it, and the controller sits. Then they are taken up to the top of the first great hill by a track. Then they are released and run through the rest of the course on the power of gravity. The tube is magnetic and permanent magnets on the cars are repelled. They cars are designed so they wrap around the tube and are kept isolated form it when the current is applied; just like a magnetic levitating train. This is the latest in three generations of roller coasters; wooden rails, steel rails, steel tube with hanging cars. In the first two generations the cars ran like little railroad cars on the tracks, but the latest generation the so called ‘flying coasters’ run on one tube and that would be the easiest to reproduce.

Once your roller coaster car goes through its loops and bends it nears the end and slows down. Then another track catches the car and tows it to the top of the last hill. Then the coaster reaches the top and falls down the hill, breaks make sure it slows down and stops right as it goes into the shed.

You could try and replicate a wooden coaster with Popsicle sticks, but you would need hundreds of them. Look at a picture of a wooden roller coaster and you will see they are massive wooden structures built with many, many X frames. The advantage of steel is less construction materials and less time will be needed to complete. However, wooden roller coasters have more of a give and sway to them so some purists prefer them. The flying roller coaster uses the latest technology and a near frictionless car connection. Only one large tube is needed (it holds a rail underneath it and that is what the car actually runs on) and you don’t have to worry about making a second rail or track that is exactly parallel to it. Other than that the three designs do the same job the same way.

I took a 1m x 1m piece of (thin) wood board for the base, and cut up wooden blocks for track support, using hot glue to piece it all together. For the track, I took black insulation piping (circular foam that goes around a pipe) and cut it in half to allow a marble to travel down the center.
