How to Make a Car Engine with Paper

Materials

• 1 sheet of paper
• Scissors
• Tape
• A pencil or pen

Instructions

1. Fold the paper in half lengthwise.
2. Cut along the fold to create two long, thin strips of paper.
3. Take one strip of paper and roll it up tightly, starting from one end.
4. When you reach the end of the strip, tape it in place.
5. Repeat steps 3 and 4 with the other strip of paper.
6. Now you have two rolled-up strips of paper. These will be the pistons for your engine.
7. Take the two strips of paper and tape them together at one end, so that they form a V-shape.
8. The point of the V-shape should be pointing up.
9. Now you have the basic shape of your engine.
10. To make the engine work, you need to add a crankshaft.
11. To do this, take a pencil or pen and poke a hole through the center of the V-shape, about 1 inch from the point.
12. This hole will be the crankshaft bearing.
13. Now you need to make the crankshaft.
14. To do this, cut a piece of paper about 2 inches long and 1 inch wide.
15. Fold the paper in half lengthwise.
16. Cut along the fold to create two long, thin strips of paper.
17. Take one strip of paper and roll it up tightly, starting from one end.
18. When you reach the end of the strip, tape it in place.
19. Repeat steps 16 and 17 with the other strip of paper.
20. Now you have two rolled-up strips of paper. These will be the crankshaft journals.
21. Take the two strips of paper and tape them together at one end, so that they form a T-shape.
22. The top of the T-shape should be pointing up.
23. Now you have the crankshaft.
24. To assemble the engine, insert the crankshaft into the crankshaft bearing.
25. The crankshaft should be able to rotate freely.
26. Now you need to add the pistons.
27. To do this, insert the pistons into the cylinders.
28. The pistons should be able to move up and down freely.
29. Now you have a complete car engine made out of paper!

Tips

• To make the engine more efficient, you can use a thicker type of paper.
• You can also add a flywheel to the crankshaft to help keep the engine running smoothly.
• If you want to make a more realistic-looking engine, you can paint it or add other details.

Conclusion

Making a car engine out of paper is a fun and easy way to learn about how engines work. It’s also a great way to get kids interested in science and engineering. So grab some paper and scissors and give it a try!
