just take an angle compass see you will see a dot on the compass on the ball in the plastic just set the dot in the middle of the angle compass and launch your beyblade 3 2 1 let it rip
It dosent do anything its just for deceration
You can buy it on eBay, Amazon.com, toywiz.com, Hasbro, beyblades.org
When using constructions(bisecting or copying and angle)
Use a protractor.
Use a ruler
You use a protractor
angle of magnetic declination
Use a protractor or bisect a 45 degree angle with a compass and a straight edge
To bisect an angle using a compass and ruler, start by placing the compass point on the vertex of the angle and drawing an arc that intersects both rays of the angle. Label the points where the arc intersects the rays as A and B. Next, without changing the compass width, place the compass point on point A and draw an arc inside the angle. Repeat this step from point B, creating two intersections of the arcs. Finally, use the ruler to draw a straight line from the vertex of the angle through the intersection of the two arcs, which will bisect the angle.
Well, honey, making an 82-degree angle with a compass is as easy as pie. Just start by drawing a straight line with your ruler. Then place the point of your compass on one end of the line and swing an arc that intersects the line. Finally, use your protractor to measure the angle between the two lines, and voila, you've got yourself an 82-degree angle. Easy peasy lemon squeezy!
