In this lesson you will learn how to make a rocket ship of improvised means in 7 simple steps. The rocket flies very high. Let’s go!
The principle of launching a rocket is as follows: a paper sleeve with a streamlined softwood head takes off due to the explosion of a combustible mixture in an engine. The engine is a paper cup filled with an explosive mixture, and the mixture is ignited by an incandescent wire made of nichrome or nickel.
Two batteries from a pocket lamp provide the electrical energy for the incandescence. An ordinary light switch or just a button from an electric bell is used to close the incandescent circuit. To make the rocket rise in a given direction, four wire guides are mounted on a wooden pad. To launch the model rocket, buy the following substances: 1) potassium nitrate; 2) sulfur – a yellow powder; 3) activated charcoal. When making a rocket, we advise to stick to a certain plan.

How to Make a Rocket Ship step-by-step
Total Time: 1 hour
Step 1 [How to Make a Rocket Ship]
Make two tubes from the drawing tracing paper by winding a strip of tracing paper with glue on a round stick with a diameter of 6-8 mm. Prepare two tubes: one for the engine (shorter) and the other for the rocket (longer). The rocket tube should be easy to put on the engine tube. When the tubes are dry, remove them from the sticks, check if the tube is tightly worn on the rocket engine. Make the top of the rocket from light wood in the form of a cone.
Prepare the motor. Insert two wooden bosses into the motor tube: one at the bottom and one at the top. Take the dimensions of the bosses from the drawing.

Prepare fuel, for which weighed saltpeter – 88 g, sulfur – 6 g, charcoal – 16 g. All these substances in bags are preliminarily well prepared. All these substances in bags pre-dry well on a hot radiator. After drying, carefully grind each reagent separately in a porcelain mortar, and then mix all three components, so that a homogeneous mixture of dark grey color is obtained.
Press the prepared mixture into the motor tube. Press in the device shown in the figure. Fill with mix to leave room for gluing lower wooden boss with hole – nozzle (diameter 2,5 – 3 mm).
Step 5 [How to Make a Rocket Ship]
After inserting the lower boss with a hole in the engine tube, drill a shallow hole in the pressed mixture with a drill bit (diameter 2,5-3 mm).
In the hole in the bottom boss insert the nichrome igniter spiral with a diameter of 0.1 mm, the ends of which are connected to two thin insulated wires ignition. Connect the two ends of the leads to the battery poles through a switch.
Step 7 [How to Make a Rocket Ship]
Now make the starting platform. This is assembled from a board and four guide wires according to the illustration. Place the model on this platform and connect the fuse to the battery and to the switch. Turn on the current – the fuse will ignite the fuel and the rocket, separated from the engine, will fly upwards.
