How do I make a laser pointer trip and push a player?

Hello there.

I have a laser pointer on my place.

It is just a tool composed of a LocalScript and a Brick with a Mesh.

Here's the LocalScript:

transparency = 0.2

lp = script.Parent
pointing = false

function Click(mouse)

    pointing = true
    while pointing do

        laser = Instance.new("Part")
        laser.formFactor = 0
        laser.BrickColor = BrickColor.new("Bright red")
        laser.Anchored = true
        laser.CanCollide = false
        laser.Size = Vector3.new(1, 1, 1)
        laser.Transparency = transparency
        hpos = lp.Handle.Position+((lp.Handle.CFrame*CFrame.fromEulerAnglesXYZ(math.pi/2, 0, 0)).lookVector/-2.5)
        dir = CFrame.new(hpos, mouse.Hit.p)
        dist = (mouse.Hit.p-hpos).magnitude
        mesh = Instance.new("CylinderMesh")
        mesh.Scale = Vector3.new(0.3, dist+0.25, 0.3)
        mesh.Parent = laser
        laser.CFrame = dir*CFrame.fromEulerAnglesXYZ(math.pi/2, 0, 0)+(dir.lookVector*dist/2)
        laser.Parent = game.Workspace.CurrentCamera
        wait()
        laser:Remove()
    end
end

function Unclick(mouse)

    pointing = false
end

function Equip(mouse)

    if mouse == nil then return end

    mouse.Button1Down:connect(function() Click(mouse) end)
    mouse.Button1Up:connect(function() Unclick(mouse) end)
end

lp.Equipped:connect(Equip)

I would kindly wish to know how to make the laser push people and make them sit when the laser is pointed at them.

I thought of and tried pasting an onTouch function from a Push tool, but it simply does not work. This said tool makes the player fly away a bit when they touch my arm.

Its script is here (yes, it is the onTouched function I tried to upload to the original laser pointer script):

door = script.Parent

function onTouch(hit)
    if hit.Parent == nil then return end
    local h = hit.Parent:FindFirstChild("Humanoid")
    if h ~= nil then
        hit.Parent.Torso.Velocity=door.CFrame.lookVector * 100 -- Push the Player back
    end
end
door.Touched:connect(onTouch)

Would you help me out, please?

Thank you.
