Solved Repeating a task with BukkitRunnable

I'm trying to create a special snowball that works like a smoke bomb, spawning vision-obstructing particles for a set amount of time. After failing with For loops, I stumbled across BukkitRunnables but (probably due to my inexperience with Java) I couldn't get it working.

This is the whole class:

Code:

package me.barrabaja.armasespeciales;
import me.barrabaja.armasespeciales.Items.ItemManager;
import org.bukkit.Particle;
import org.bukkit.entity.Player;
import org.bukkit.entity.Snowball;
import org.bukkit.entity.ThrowableProjectile;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.ProjectileHitEvent;
import org.bukkit.scheduler.BukkitRunnable;


public class BombaHumo implements Listener {

    Main plugin;

    public BombaHumo(Main plugin){
        this.plugin = plugin;
    }

    @EventHandler
    public void humo (ProjectileHitEvent e){
        if (e.getEntity() instanceof Snowball) {
            ThrowableProjectile s = (Snowball) e.getEntity();
            Player p = (Player) s.getShooter();
            if (s.getItem().getItemMeta().equals(ItemManager.humo.getItemMeta())) {
                for (int i = 0; i < 10; i++) {
                    new BukkitRunnable(){
                        public void run(){
                            p.getWorld().spawnParticle(Particle.EXPLOSION_HUGE, s.getLocation(),20 , 5, 3, 5);
                        }
                    }.runTaskTimer(plugin, 0L, 20L);
                }
            }
        }
    }
}

I'm pretty sure I did a lot of things wrong here, so any help is super helpful!
