I tried making a part appear and disappear in the workspace but it didn't work?

I tried making a part that gives the players a jumpboost when they stepped on it. I stored it in the ReplicatedStorage so I can clone the jumpboost part and put it in the workspace. First the part will spawn in the workspace, and then it will give the player that touched the part a jumpboost, and then the part would proceed by destroying itself when it has been touched by the player and respawn again in the workspace. Unfortunately, it didn't work. The part didn't seem to spawn in. Here's the script:

local jumpBoost = game.ReplicatedStorage:FindFirstChild("JumpBoost")
local clonedJumpBoost = jumpBoost:Clone()
clonedJumpBoost.Parent = workspace
local boostPart = game.ReplicatedStorage.JumpBoost
local boostedJumpPower = 100
local function onPartTouch(otherPart)
	local partParent = otherPart.Parent
	local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
	if ( humanoid ) then
		boostPart.CanCollide = false
		local currentJumpPower = humanoid.JumpPower
		if currentJumpPower < boostedJumpPower then
			humanoid.JumpPower = boostedJumpPower
			boostPart:Destroy()
			wait(10)
			humanoid.JumpPower = currentJumpPower
		end
	end
end
boostPart.Touched:Connect(onPartTouch)
clonedJumpBoost.Parent = game.Workspace

remade script with respawning the part, script doesn't work in ReplicatedStorage i recommend placing it in ServerScriptStorage, set the respawn value to false will stop the respawning

local jumpBoost = game.ReplicatedStorage:FindFirstChild("JumpBoost")
local clonedJumpBoost = jumpBoost:Clone()
clonedJumpBoost.Parent = workspace
local boostedJumpPower = 100
local respawn = true --set to false to disable respawning
local function respawn()
	if respawn then
		local jumpBoost2 = game.ReplicatedStorage:FindFirstChild('JumpBoost')
		local clonedJumpBoost2 = jumpBoost2:Clone()
		clonedJumpBoost2.Parent = workspace
		local boostedJumpPower = 100
		local function onPartTouch2(otherPart)
		    local partParent = otherPart.Parent
		    local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
		    if humanoid then
		        clonedJumpBoost2.CanCollide = false
		        local currentJumpPower = humanoid.JumpPower
		        if currentJumpPower < boostedJumpPower then
		            humanoid.JumpPower = boostedJumpPower
		            clonedJumpBoost2:Destroy()
		            wait(10)
		            humanoid.JumpPower = currentJumpPower
					wait(1)
					respawn()
		        end
		    end
		end
		clonedJumpBoost2.Touched:Connect(onPartTouch2)
	else
		return
	end
end
local function onPartTouch(otherPart)
    local partParent = otherPart.Parent
    local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
    if humanoid then
        clonedJumpBoost.CanCollide = false
        local currentJumpPower = humanoid.JumpPower
        if currentJumpPower < boostedJumpPower then
            humanoid.JumpPower = boostedJumpPower
            clonedJumpBoost:Destroy()
            wait(10)
            humanoid.JumpPower = currentJumpPower
			wait(1)
			respawn()
        end
    end
end
clonedJumpBoost.Touched:Connect(onPartTouch)
