Why particles are invisible for a other players?

local uis = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local char = player.Character

uis.InputBegan:Connect(function(input, gameProcessedEvent)
    if input.UserInputType == Enum.UserInputType.Keyboard then
        if input.KeyCode == Enum.KeyCode.Z then
            print("Vso okay")
            local bups = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups1 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups2 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups3 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups4 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups5 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups6 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups7 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups8 = game.ReplicatedStorage.ParticleEmitter:Clone()
            local bups9 = game.ReplicatedStorage.ParticleEmitter:Clone()
            bups.Parent = char.LeftHand
            bups1.Parent = char.LeftHand
            bups2.Parent = char.LeftHand
            bups3.Parent = char.LeftHand
            bups4.Parent = char.LeftHand
            bups5.Parent = char.LeftHand
            bups6.Parent = char.LeftHand
            bups7.Parent = char.LeftHand
            bups8.Parent = char.LeftHand
            bups9.Parent = char.LeftHand
            script.Parent.MouseGiver.Disabled = false
        end 
    end
end)
uis.InputEnded:Connect(function(input, gameProcessedEvent)
    if input.UserInputType == Enum.UserInputType.Keyboard then
        if input.KeyCode == Enum.KeyCode.Z then
            print("Vso ploha")

            for i = 1,15 do
                wait(.0001)
                char.LeftHand.ParticleEmitter:Destroy()
                char.RightHand.ParticleEmitter:Destroy()
                script.Parent.MouseGiver.Disabled = true
            end
        end 
    end
end)

When i am activaiting fire, other players don't see him. Why?
