What could be a better gift for a sailor on Defender's Day than a ship model? Let the simplest, but made by hand! A chic model of a submarine is easy to make from the simplest and most unexpected materials.
You will need:
- case from a big cracker;
- a smooth plastic ball (Christmas tree, for example), suitable for a cracker in diameter;
- a cap from an antiperspirant (the cap from Mennen Speed Stick is ideal in shape);
- cardboard;
- tin cover from conservation;
- 1 match;
- 1 cotton swab;
- scissors;
- awl;
- glue;
- black paint in a can.
Manufacturing:
The hull of the boat will be a cracker on which all other parts of the submarine are attached.
We cut a hole approximately in the middle of the cracker body into which we insert a cap - a cabin (fencing of retractable devices).
We make the stern of the boat from a cardboard cone. We also cut out rudders, bow and stern depth rudders from cardboard.
You can fix the steering wheels by making protrusions on them and slots in the body: this is more reliable, but more difficult. It is easier to bend the edges and glue the tail to the cone.
From the tin cover with scissors (not manicure, but good scissors for cutting), we cut out the screw. Having bent the blades, we make a hole in the center with an awl and fix the screw on the stern with the help of an axis made of a match. The propeller of the submarine is even spinning! If it's hard to make 6 blades, try three or four. 
We glue the aft part with the hull - the most difficult part of the work is done!
The nose part is much easier to make: you just need to put the ball into the cracker body about halfway and fasten it tightly. Get a rounded bow of the submarine.
Stepping back a little, we glue the bow depth rudders.
Having made two holes in the roof of the superstructure with an awl red-hot on fire, we insert an antenna and a periscope made from a cotton swab rod: one is shorter, the other is longer.
The assembly is over, it's time to start painting.
The fastest and easiest way to paint our boat is from a spray can. What a beauty this is! Only the tail number is missing.
Do-it-yourself submarine, military-themed craft
The active development of underwater shipbuilding can be attributed to the 17th century, although the idea itself is rooted in ancient times. William Bowry, Cornelius van Drebbel, Robert Fulton proposed new projects for a submarine, tested it and modified it. In practice, the first boats were used by the Americans during the Civil War in the late 18th century. After only two centuries, submarines began to be introduced into the navies of many countries and played an important role in wars, as well as during the exploration of the deep sea. We suggest you make an original DIY submarine craft.

Master class: do-it-yourself submarine
1) Empty the contents of the cracker. Circle the antiperspirant cap on the surface of the cracker and cut a hole. Glue the cap to the cracker and you will have a felling. You can make holes in the cap with an awl and insert an antenna or a periscope, which are easy to construct from cotton swabs.
2) You need to make a cone out of cardboard so that its base is equal to the diameter of the cracker. This cone will become the stern of our submarine.
3) Cut out the blades for the stern from cardboard, which will act as rudders, as well as bow and stern rudders.
4) Glue the cardboard parts on the cone, you can make slots so that the parts hold more securely. Bow rudders are glued to the bow of the boat.
5) Cut out a 6-blade propeller from a tin can and bend them slightly. Make a hole in the center and insert a match into it. Attach the screw to the stern.
6) Now it remains to paint the finished product. It is very convenient to use an aerosol can, but acrylic paints are also suitable. The submarine looks original in black, but you can make it gray or green.
7) Draw the side number with white acrylic paint or corrector. You can also print or cut out the numbers. If you want to give someone a submarine, you can also draw or paste the name of the future owner of the submarine as well as the tail number.

INSTRUCTIONS
Creating a propeller
1. To start making a propeller, you need to cut off the bottom half from a 2 liter plastic bottle. Cut the bottom of the bottle as shown in the howtoons.com instructions to make the shape of a screw that has five separate blades. It's quite difficult because the plastic is thick in some places. Ask an adult to help you cut out these blades with a sharp knife. Figure 2 shows the finished screw.
Figure 2 - Submarine propeller
2. Have an adult make a hole in the bottle cap and two holes in the propeller, one in the center and one just outside the center. This can be done with an awl or a needle by holding it over the fire of the stove.
3. Use scissors to cut out a small plastic circle from the remains of a 2 liter plastic bottle. The circle should be about the same size and shape as the cap of a small water bottle. This part will go between the bottle cap and the propeller, and will serve as a washer that the propeller will slide on as it rotates. With a needle, carefully make a hole in the middle, such that the tip of the paper clip can fit through. Be careful if you're using a needle so you don't prick yourself.
4. Straighten one end of the paperclip and thread it through the hole in the top of the bottle cap, then through the washer, and finally through the center hole of the screw. The propeller fins, bent away from the bottle cap, should point down.
5. Using pliers, bend the paperclip and secure it to the bottle by threading it through the second hole.
6. Next, you need to put a scale on the bottle with a marker to make it easier to fill the submarine with different amounts of water during testing. Using a measuring cup, add 20 ml of water to the bottle, each time marking the water level in the bottle with a marker. When you are done, you can sign these lines (20 ml, 40 ml, 60 ml,…, 500 ml).
Creation of a submarine
1. Punch two small holes in the bottom of the bottle, like the holes in the propeller, one in the center and one slightly off-center.
2. Straighten one end of the second paper clip and use chopsticks to insert the straight end of the paper clip through the neck of the bottle into the hole in the bottom of the bottle. This step requires patience and skill!
3. Once you have the straight end of the paperclip in the hole, use your pliers to bend the end again and thread it into another hole that is off-center to secure the paperclip.
4. Use your chopsticks again to put the elastic on the hook of the paperclip inside the bottle.
5. Without releasing the elastic, hook the other end of the elastic onto the hook of the paperclip inside the bottle cap screw. If it is too difficult to pull the elastic band out with chopsticks, use a wire hook to pull it out. Make sure the rubber band inside the bottle is tight enough. If the elastic band is too loose, try a smaller elastic band. And here is our submarine assembled (with a propeller attached to it).

Sometimes you really want to do something with your own hands, so that it is both interesting and spiritually satisfying.
But in fact, in order to do something, you need a bunch of tools, and you also need material, which is always not at hand, and you need money for this material.
And here is the usual model of two plastic water bottles, a couple of paper clips and an elastic band, with which we drag the money.
In order; to create this toy, you still need something - namely, two bottles, a drill - you will have to drill, or you can dig holes, the old fashioned way. A couple of paper clips or wire, and most importantly - a knife. Yes, a couple of boards, from under ice cream, sticks will do just right. And do not forget the gum, you will need it for the rubber motor.
So, when everything you need has been collected to the heap, then you can start. The first thing to start with is to make a screw, without it, our boat will not float.
It makes no sense to tell how to make a screw, according to the drawing, it’s clear.
The more precisely we make the screw, the more likely it is that the boat will float. This is where you need a staple.
The main thing not to forget is to lay something like a thick washer between the screw and the cover, you can use a bead ball.
When the main assembly is assembled, we take the second plastic one and drill or pick a hole in the bottom with a nail.
Now we need a second paper clip, which we fasten in the form of a loop for a hole in the bottom of the bottle.
You can see everything in the picture. Do not forget to fasten an elastic band in advance and preferably more than one, the thicker the rubber band, the stronger the thrust of the submarine.
You can now assemble the structure to a heap, we hook the elastic band on the hook on the screw and tighten the cover with the screw. It remains only to fix the stabilizers, they are needed so that the model does not turn over in the water.
It should turn out something like this.
Yes, the most important thing is that the boat floats - you need to use the handles - we hold one by the frame, and the other we wind the screw, in which direction it does not matter - it will be visible there, during the voyage. After the screw is screwed, we lower the boat into the water and lower it. Nothing complicated. If everything was done at least 50% correctly, it should float. Well, you understand me: smile .:
And now you can start testing, so that the boat floats under water by experimenting by adding water to the bottle.
I don’t know about adults, but the children will be delighted.
