Made a script that didn't work was curious why.
( not full script )
for i, v in pairs(particle) do if v:IsA("ParticleEmitter") then v:Destroy() end end
ParticleEmitter. The ClassName is literally ParticleEmitter.

It's just "ParticleEmitter", if you want to see just look at the properties of the Instance and find "ClassName"
