Advice 1: How to make a rocket at home

Rocket is not just a toy. This is a real aircraft which works on the same principle as a real rocket. The launch of such missiles could become a worthy conclusion of the day.
A toy rocket flies just like a real
Instruction
1
Make fuel mixture, chuckle nitrate, charcoal and sulfur in the correct proportions to Make a mixture of the wick by mixing saltpeter and sulfur at the rate of 9 parts nitrate to 1 part of sulfur.
2
Drill out the metal part of the casings from the fixing capsule. Remove the fasteners capsule.
3
In the Board hammer the nail in. The nail should protrude 2 cm above the Board. Raised Knez nail gently grind, giving it a smooth tapered contours. The sharp end is slightly blunted.
4
Carefully remove any metal filings. Put the sleeve the metal part on the nail and cover it well-mixed fuel at ¾ height.

Using a wooden round stick extrude the fuel in the sleeve, lightly hitting it with a mallet.
5
Cut out writing paper circle slightly larger internal diameter of the sleeve. It needs to completely close the fuel layer. On top of the resulting partitions pour fuel mixture with a layer of 0.5 cm and seal the liner top layer of thin paper. This charge is for the discharge chute.
6
Take a round stick of larger diameter. Wrap it with a layer of newsprint. Secure with glue and let dry. Then lightly soak the newspaper layer of oil and wipe off.
7
Wrap the resulting preform is a tube of drawing paper 2-spiral thick. Carefully RUB each round with glue. Dry the tube on the stick.

Remove the tube from the stick. Remove the layer of newsprint, it is no longer needed.
The approximate size of the rocket
8
From the soft wood, make the cone of the rocket. It is a tube with a length of 6-7 cm, the upper end of which falls on the taper and rounded ends, and the bottom 1-1. 5 cm is inserted firmly into the upper part of the paper tube. You poluchili the body of the rocket and fairing.
9
Make of paper stabilizers. There should be at least three. They represent the triangles and must have a soul connection with a rocket. Stabilizers to the body of the rocket fasten with glue. From the end of the cone that is inserted in the body of the rocket, fasten a metal ring or bracket inner diameter of 0.5 cm, made of steel wire. Close the jump ring. It serves to attach the parachute.
the drawing of the stabilizer
10
Insert the core-the engine in the lower part of the rocket. It must be tightly and go back to the requirement. If the engine is poorly kept, from the inside: glue the extra paper ring is 3 cm wide and Completely dry the hull. Paint it with waterproof paint in a bright color.
11
Make a parachute. The diameter of the dome of 15-20 cm For this model to apply tape chute. One end of the ribbon attach to a wooden stick. To the ends of the sticks, attach the loop of string with a length of 10 cm To one end of the loop tie a piece of aviation rubber with a length of 10 cm. the End of rubber thread and tie around the wire ring, to put on the fairing. Additionally secure it using a normal thread. The ring fairing tie another thread a length of 10 cm also tie a piece of aircraft tires, but it still is 5 cm normal thread. Fasten the thread on the inner side of the rocket body in three inches from the upper end of the tube body. You can skip through the entire body, making a hole in it and paste over for the strength of the paper ring.
12
Lay the parachute. To do this, wind the tape into a roll, starting from the free side. Press the coil with the wand, which is attached parachute. Gently slide the resulting coil in the body of the rocket. Lay on top of ribbon and thread mounting to the fairing. Close the design of the fairing.
13
Make a starter device. Cut a piece of iron wire of length 120 cm of paper on the wire glue 2 of a cylinder 1 cm long and with a diameter slightly larger than the diameter of the wire. The ring should slide freely on the wire. Received ring clip on one of the longitudinal lines on the body of the rocket durable glue. One ring hook at the junction of the housing with the stabilizer, and the other in the upper part about 1 cm from the fairing. The rocket should slide freely on the wire. At a distance of 50 cm from one end of the wire wrap it restrictive ring from any wire. The way please this ring the rocket to fall should not be. This side of the wire to stick into the ground.
14
Make the fuse. You can get a fuse from firecrackers or fireworks, but the length may be insufficient. Make stopin. Take the cotton thread and fold it 6 times. Supposed to be a segment of length 8 cm. Cook the paste. Moisten the thread of the starch paste. Dip its whole length in a composition similar to fuel, but no coal. The threads should stick a layer of the composition. The cord dry.
15
Before you start, insert the engine into the rocket. Before to paste it in the body of the rocket, insert the wad. Wad can be a piece of foam. Bend the cord at one end and insert this end into the nozzle. The rocket is ready

Advice 2: How to make a fairing

Fairing quite useful and necessary thing for people who love speed. To make this design easy and at home, the main thing – desire. Manufacturer of fairing for motorcycle will take you no more than an hour.
How to make a fairing
You will need
  • - plaster
  • - thin saw
  • - rude files
  • - sharp boot knife
  • - PVA glue
  • - epoxy glue
  • - fiberglass
  • - plaster
  • - emery emery cloth
  • - primer
Instruction
1
Manufacture of foam required shape of the fairing. In the manufacture of mold fairing use rigid foam (for processing use the grater for vegetables). The shape of the fairing, it is recommended to choose in the form of cases closed (with cap). In this case think of how to make a frame, at least on the side that will be attached to the motorcycle.
2
After sizing, the cases cut with a thin saw along the parting line of the cover along with the foam shape. Ready shape try on the motorcycle at the point of attachment.
3
The resulting form of the cone must be luted. Use two-component polyester putty. If necessary, treat it with a file and sandpaper.
4
Form grease with mastic for rubbing parquet or paraffin dissolved in gasoline.
5
Fiberglass soaked in epoxy glue at a ratio of 1:1 (by weight). A sheet of glass and a piece of linoleum put fiberglass on it, pour in a thin stream over the entire surface, epoxy glue and smear it. Wait 3-5 minutes until the glue will impregnate the fabric. Then place it on a greased form, repeating, thus, 3-4 layers of fabric.

How to make a firecracker at home
You will need
  • Plastic bottle, box of matches, a stapler, peas, scissors, tape, foil.
Instruction
1
First, you need to make the igniter. To do this, take a strip from the plastic bottle and put on her half of the side walls of the box of matches. To fix a stapler in two or three places.
2
As for the case of the firecrackers, take the balloon to a small size. The ball must be filled with peas. You can use the funnel made from the neck of a plastic bottle, and scoop out a small Cup. Merc gives you the opportunity each time to measure and pour the same amount of peas.
3

From one end to leave a flammable part of the exposed in the place where he is closer to the edge of the firecrackers. Remove the funnel, trim the neck on the ball inserted between a firecracker and a ball of five matches.
5
The firecracker tape ball matches and immediately attach the igniter. The tip of the igniters to bend, so it does not hit the ball. Petard is ready.
Note
Attention! Making firecrackers at home is extremely dangerous and is not recommended by the author of this article. Information is given for informational purposes only.

Rubber petard has disadvantages: it can burst, if you get caught or run into a sharp object. Therefore, on top of rubber put on the shell of the foil. For this the ball is applied a piece of foil, and then a common envelope. Foil to flatten, giving it the shape of a ball.
Useful advice
Make sure that the heads of the matches were located directly in front of an open igniter.

Advice 4: Foam: how to make it at home

The foam can be done independently at home. You do not even need special equipment. However, as such, self-made, foam may be very mediocre.
Foam: how to make it at home
You will need
  • polystyrene
Instruction
1
To make foam, take a lot of polystyrene balls and fill their container. (Apparently these little balls resemble beads).
2
To the polystyrene balls were glued together, heat them very hot steam. The heat the bulbs produce until, until they begin to swell. After the balloons are inflated, they will approach each other, coalesce and take the form of a container.
3
After cooling, the resulting mass of foam can be considered ready. If you have produced any shape, remove the foam from the tank (capacity in this case will have to dismantle or break). If the foam is suitable for insulation, then leave it in between the walls.
4
To get a real, high quality foam, you will need special equipment and a workshop. Easier and more profitable to produce urea foam.
For manufacturing prepare solution, having dissolved in water at room temperature a blowing agent and a curing catalyst. Start the installation. Pour the foaming agent solution and the resin in the tank. Feed the input of compressed air. Turn on the pumps. Open the taps with the words "solution" and "resin". Pour the resulting penomassu in a special form. Cut and dry foam obtained (this may take up to three days).
Note
The room must be well ventilated as in the production of foam formed toxic substance formaldehyde.
