How to Make a Paper Submarine?

Introduction

Making a paper submarine is a fun and creative activity that can be enjoyed by people of all ages. With just a few simple materials and some basic folding techniques, you can create a fully functional paper submarine that can dive and resurface in water. In this article, we will guide you through the step-by-step process of making a paper submarine.

Materials Needed

Before we begin, you will need the following materials:

• One piece of paper (preferably A4 or letter-sized)
• A pencil or a ruler
• A eraser
• A paperclip
• A pair of scissors
• Glue or tape
• Water

Step 1: Design the Submarine

The first step in making a paper submarine is to design the basic shape of the submarine. You can use a piece of paper to draw the outline of the submarine. Make sure to include the following features:

• Nose: The nose of the submarine should be pointed and should be about 1-2 cm long.

• Body: The body of the submarine should be cylindrical and should be about 5-7 cm long.
• Tail: The tail of the submarine should be flat and should be about 1-2 cm long.
• Hatches: The hatches of the submarine should be small and should be located on either side of the body.

Step 2: Cut Out the Submarine

Using your scissors, cut out the submarine along the lines you drew in Step 1. Make sure to cut carefully and accurately, as this will affect the stability and functionality of the submarine.

Step 3: Create the Propeller

The propeller is an essential part of the submarine, as it helps to propel the submarine through the water. To create the propeller, cut out a small piece of paper and shape it into a spiral. Attach the propeller to the tail of the submarine using glue or tape.

Step 4: Create the Ballast

The ballast is a small weight that is used to balance the submarine. To create the ballast, cut out a small piece of paper and fill it with small stones or beads. Attach the ballast to the nose of the submarine using glue or tape.

Step 5: Assemble the Submarine

Using your hands, assemble the submarine by attaching the body to the nose and tail. Make sure that the body is securely attached to the nose and tail, as this will affect the stability of the submarine.

Step 6: Test the Submarine

To test the submarine, place it in a large container of water and observe how it behaves. Make any necessary adjustments to the ballast or propeller to ensure that the submarine dives and resurfaces smoothly.

Tips and Variations

Here are some tips and variations to help you improve your paper submarine:

• Use different types of paper: Experiment with different types of paper to see how it affects the stability and functionality of the submarine.
• Add a cockpit: Add a small cockpit to the nose of the submarine to create a more realistic design.
• Use a different propeller: Experiment with different types of propellers, such as a spiral or a wing-shaped propeller, to see how it affects the performance of the submarine.
• Add a parachute: Add a small parachute to the tail of the submarine to create a more realistic design.

Troubleshooting

If your paper submarine is not diving or resurfacing as expected, here are some common problems and solutions:

• The submarine is too heavy: Check if the ballast is too heavy and adjust it accordingly.
• The submarine is too light: Check if the ballast is too light and adjust it accordingly.
• The propeller is not functioning: Check if the propeller is clogged or damaged and replace it with a new one.
• The submarine is not stable: Check if the body is not securely attached to the nose and tail and adjust it accordingly.

Conclusion

Making a paper submarine is a fun and creative activity that requires some basic folding techniques and materials. By following the steps outlined in this article, you can create a fully functional paper submarine that can dive and resurface in water. Remember to experiment with different designs and materials to improve your paper submarine and to troubleshoot any problems that may arise.
