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?
