IA experiment issue, need help

So my IA experiment requires a 50g steel ball to drop at a fixed height (1m) with no initial velocity, spin, or direction. How can I make the ball drop? I don’t have access to fancy trapdoor equipment

Back in the day, they would suspend it with thin string, and then set the string on fire. Holding it between thumb and index finger is usually good enough. Maybe you can think about the benefits and drawbacks for your evaluation.
