We make a model of a pulsating Reynst jet engine

In the vastness of the world wide web you can find many forums and discussions that relate to this type of engine. However, before that it was impossible to find Russian-language instructions for the manufacture of a pulsating jet engine, since only all the video and text materials were in English. Fortunately, our long searches were successful, and we present to you a material in which a review of the Russian-language video on the manufacture of the Reinst engine is made.

What do we need for assembly:
- glass jar of 400 ml;
- a can of condensed milk;
- copper wire;
- alcohol;
- scissors;
- compass;
- pliers;
- dremel;
- paper;
- a pencil.

Just note that from a can of condensed milk we need only a side tin. Also, we’ll clarify that if you don’t have a nap, you can use an ordinary awl, since we need a hole with a small diameter. You can start assembling the engine.

First, make a hole with a diameter of about 12 mm in the glass jar lid. Why approximately? The fact is that there are simply no exact formulas for assembling such an engine.

After that we need to roll up the diffuser. To do this, take the paper and draw a template on it, as shown in the figure below. You need to draw a template with a compass. Measure the following: the nearest radius from the middle is approximately 6 cm, the farthest is 10.5 cm. After that, we measure 6 cm from the resulting sector. At the near radius, we cut it off.

We apply the resulting template on a tin from a can of condensed milk and circle.

After that, cut out the resulting part with scissors.

We bend a millimeter from two edges in different directions.

Now we form a cone and engage the bent parts for each other.

Our diffuser is ready.

Now we drill holes from four sides on the narrow part of the diffuser.

We do the same on the lid around the central hole.

Now, with the help of a wire, we hang our diffuser under the hole in the lid.The distance from the top edge should be approximately 5-7 mm.

Next, pour alcohol into our jar, about 5 mm from the bottom.

Close the lid. It remains only to light the alcohol with a match. We also add that acetone can be used as an alternative to alcohol.
