How To Draw Perfect Dotted Lines 🤔

Have you ever wondered how some people can draw a perfectly dotted chalk line? Well, most people think it's by rapidly moving your hand up and down. But this just creates uneven gaps and messy dots. Instead, hold the chalk by the end and angle it at 45 degrees in the direction you're drawing. As you move your hand, the friction between the chalk and the chalkboard makes it bounce naturally, and this creates evenly spaced gaps, leaving you with a perfect dotted line.
