How do i make the kill part fire more than once?

I have scripted a part to fly from the characters lookvector at a certain velocity. My problem is that the damage part only works on the first part created. How do i make it so it works in all the created parts and just not the first one

here is my code:

s = game:GetService("ServerStorage")
tool = script.Parent
part = Instance.new("Part")
player = game.Players.LocalPlayer
stat = "undone"
h = "nope"

print("im black")
tool.Equipped:connect(function(mouse)
    mouse.KeyDown:connect(function(key)
        if stat == "undone" and key == "m" then
            stat = "done"
        print(key)
        part.Transparency = .5
        part.CanCollide = false
        print(mouse.hit)

        local float = Instance.new("BodyPosition",part)
        float.MaxForce = Vector3.new(0,102999,0)
        local f = Instance.new("Fire",part)
        f.Color = Color3.new(0,0,0)
        f.SecondaryColor = Color3.new(255,0,0)
        f.Heat = 25
        f.Size = 30
        local f1 = Instance.new("Fire",part)
        f1.Color = Color3.new(0,0,0)
        f1.SecondaryColor = Color3.new(255,0,0)
        f1.Heat = 25
        f1.Size = 30
        local f2 = Instance.new("Fire",part)
        f2.Color = Color3.new(0,0,0)
        f2.SecondaryColor = Color3.new(255,0,0)
        f2.Heat = 25
