How to send a firework in the air? [closed]

Here is a script I made, that will send a rocket up at a decent speed with and explosion, and firework noise. Keep in mind I used a button(ClickDetector) so you may have to change the way the script is executed, if you want to make it fire when a player simply touches it.

local button = script.Parent
local Firework = script.Parent.Parent.Part


function makesound()
    local sound = Instance.new("Sound") -- makes the sound a thing
sound.SoundId = "http://www.roblox.com/asset/?id=138080762"  -- the firework sound it makes
sound.Parent = game.Workspace -- makes the sound a part of the rocket 
sound:Play() -- plays the noise as implied
end

function mexplosion() -- function that creates explosion
    local cracker = Instance.new("Explosion") -- actually makes the explosion existent
    cracker.Parent = workspace -- makes the explosion'tangible'
    cracker.Position = Firework.Position -- makes the explosion happen at the exact location of the rocket 
    cracker.BlastRadius = 8 -- size of blast radius
    cracker.BlastPressure = 5e+005  -- power of blast
end

function onClicked() --im using a button for this
    wait(1)
    for i = 1,130 do --how far up you want it to go
    Firework.Position = Firework.Position + Vector3.new (0,1,0) -- takes its current position and adds plus 1 on the y axis to it as fast as possible until it reaches the hight limit
    wait()
    end
    mexplosion() -- makes it explode
    makesound() --Makes the firework noise
    Firework:Destroy() -- makes it appear the explosion destroyed the rocket
end

script.Parent.ClickDetector.MouseClick:connect(onClicked) -- connecting the button
