Easy steps to build a compass.
• Three pencils, preferably two of the same size and one shorter. The two long ones need to be longer and have a pointy edge. The short one does not matter if its sharpened or not. • Ten small rubber bands. Only 3 will be used but if one breaks, it is better to have more available. • A sheet or paper to draw the circle on.

Place the two long pencils next to each other with the tips facing down.
Step 2: Tie Long Pencils
Take a rubber band and tie the two long pencils together by the end of the erasers.
Step 3: Separate Pencils
Form an X by separating the tips of the pencils in opposite directions.
Step 4: Tie the Third Pencil
Take the third pencil, and with another rubber band, tie the part where the yellow part of the pencil begins with the start of the yellow part of a long pencil.
Step 5: Do the Same With the Other Side of the Pencil
Take the other end of the short pencil and, with another rubber band, tie it with the other long pencil at the same height to form a triangle.
Step 6: Check Rubber Bands
Ensure that all of the rubber bands are well placed so that they do not slip.
Step 7: Raise Short Pencil
Raise the short pencil up, approximately 2 inches.
Step 8: Adjust Size
Adjust the size of the circle by moving one of the long pencils toward the center or out of the short pencil.
Step 9: Hold Compass
Hold the compass by the middle section.
Step 10: Put Compass on Paper
Rest the compass on a sheet of paper.
Step 11: Put Pressure
Put more pressure on one long pencil, which will mark the center of the circle
Step 12: Rotate Paper
Rotate the paper slowly until forming a complete circle.
Congratulations! You have successfully build a homemade compass.
