how to make a homemade rocket? show me the picture of the model.?

Take a look at the pyrotechnics chapter of this side.\n\nhttp://www.vk2zay.net/\n\nCareful: it is neither simple nor without danger.

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask. It is done by using the principles of the kinetic theory of matter.\nAnother cool project might be doing something with dry ice. Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions. Make some dye molecules or something.\n\nHope one of these ideas works for you.

creating a physical model of something (a project).\nex: mount rushmore\n\n...theres alot of details that you need to include when carving it.

Well it is pretty easy to build a simple motor. There are instructions at this website.

Lots of variables here. Do you want one that will move with directional intent, or one that just floats?\n\nThe simplest method for making a "hovering" vehicle would be to take the vacuum engine, mount it onto a curved shield, with the curvature facing down. Make sure your shield is a very light material, balsa wood works, i suppose.\n\nIf you know where the vacuum's intake and output valves are, then it's easy. make sure you make a hole for the output, and secure the engine to the top of the shield. Turn on the engine, and watch the contraption float around aimlessly. It's basically how a air hockey table works, except in reverse.\n\nEDIT: one important detail. Are you trying to make a hover car strong enough to hold your weight? Because that would need one hell of an engine.

Check out Estes Rockets and buy a complete kit, easiest way to get started.  Should be available in local stores also.

Something that may be fun is a project with model rockets. Give them the necessary information to calculate the height of the rocket, based on the rocket engine and mass of the rocket as homework.\n\nThen at school, fire a few of them and using basic trig calculate the height and see how close they are.\n\nRocket engines are typically rate something like: A8-3 which breaks down as follows:\nA --> 2.50 Newton-seconds of power\n8 --> average thrust (in newtons)\n3 --> seconds from end of thrust to ejection charge (parachute)\n\nThe engines also have a time-thrust curve that shows how the power is delivered over time. Check the following link below for some more info:\n\n------------------------------------------------------------------------\n\nHere is another one:\nNot sure how readily available props are for you but if you can hook up a camera in a room with a strobe light/flash and then set up a collision (air hockey table or pool table come to mind) then you can calculate the velocity of each object, measure its mass and then demonstrate the conservation of momentum using vectors. Because you know the frequency of the strobe, and the distance traveled, you can compute the vector velocity.\n\nOr how about:\nFirst, fire an arrow down a football field. Given the amount of time aloft calculate the initial velocity (ignore air resistance/friction) Then fire an arrow at a bale of hay (extend the bow by the same amount) and measure how far into the bale the arrow went. Using the same initial velocity and distance into bale, calculate the rate of deceleration and coefficient of friction of the hay bale.

You mean like a model rocket?\nTry Estes Industries at the site below.  They have been in the business for decades and have a wide variety of models from which to choose.  Check with your local laws first.  These are not legal everywhere.

its pretty simple.\nyou need a pvc or pvp or whatever the fuck its called,pipe. some hairspray(seriously) a potato and a match. spray mad hairspray at the bottom of the pipe, insert potato. and light it up. (the tricky part is introducing the flame to the fuel.

not pure sugar, but you can mix the sugar with a potassium powder and put that into model rocket engines and it will launch if you mixed it right.

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

no styrofoam??? aww that ruins some of the fun! i love crafty projects tho. okay you can use bakeable clay. it comes in a variety of colors and can be molded into many shapes. i would suggest working from the inside out and making it into a circle with a pie shaped cutout in it so you can see inside. basically you would make the clay figure and then bake it. you can spray it with a glossy finish and tadaa! oh, and to hang it from the ceiling? i guess you would need to screw in a metal hook beforehand. good luck!!

Either draw it and scan it or if you are making it on the computer i would say adobe photoshop. If you want to try and animate it then some flash program - maybe fireworks??

Here's one way.  I built something like this when I was 11.\n\nI dont need to say the obvious about not cutting off your fingers, poking your eyes out, or gluing your hands to the table do I?\n\nie I'm assuming you're capable of doing the below safely.\n\nyou need:\n\n2 big wheels\n1 smaller wheel (you can always make wheels from cardboard and balsa)\nThe biggest propeller thats fits.\nelectric motor\nlantern battery (big square thing with springs on the top)\nSome 1/8" thick balsa sheet.\nsome dowel which fits in the wheel.\nwire\nA wide necked plastic drinks bottle - Sunny D maybe?\nsticky tape \nhot melt glue \nlong drawing pins/nails\n2 x 10-20 ml syringes and a length of narrow bore plastic tube.  (doctors surgery might give you two syringes if you ask nicely an the tube is used on fish tanks)\n\n\nThe plastic drinks bottle is going to be the chassis for your car.\n\nyou need to cut the following holes in it\n\n- small hole in the lid \n\n- Big hole in the side just smaller than the tennis ball\n\n- Small hole for the wires from the motor\n\n- small rectangle opposite the big hole, near the bottom of  the bottle, same width and length as the small wheel.\n\n- 2 small holes the same diameter as the dowel further up\n\n\nHot melt the motor to the inside of the lid with the shaft sticking through the hole.\n\nSecure the propellor to the front of it. \n\ncut two long lengths of wire.  Strip the ends and twist one wire around each of the terminals on the motor.\n\nFit the cap, motor & propellor wires.  push the motor wires though the bottle.\n\nPut a short length of dowel through the small wheel and then hot melt it inside the plastic bottle so the wheel sticks down through the hole you made.\n\nStick a long piece of Dowel through the two small holes at the front.  And pin the wheels on the axles.  All the Wheels rotate freely.\n\nHot melt  another piece of dowel to the bottom of the bottle so that it sticks up vertically.\n\nMake a rudder out of the 1/8" balsa. say 6" high and 3" deep.  Near the bottom stick a 1/2" long piece of dowel so that pokes out at 90°.\n\nTape the balsa to the vertical dowel along one side only so that it will hinge.\n\nHot melt a syringe to the top of the bottle so that the plunger is facing the rudder.  Attach a piece of dowel to the syringe plunger and then to the short bit of dowel sticking out of the rudder.  the rudder end needs to be able to move  ie pinned together.\n\nConnect the syringe to the plastic tube.\n\nWrap the wire from the motor and the tube together with tape to make an umbilical cord. \n\nconnect the other end of the tube to the syringe\n\nConnecting the battery up will give you forwards and reverse and pushing the syringe in and out will give you steering.\n\nThe tennis ball will just sit in the hole on top.

use a CD and the top of a soda bottle (both the cap and the very top) glue the cap to the CD (you need a VERY small hole in the cap) and put the balloon on the very top of the bottle, use that to blow the balloon up
