How to get the part that a ray hits?

local handle = script.Parent.Handle

script.Parent.Activated:Connect(function()
    local plr = game.Players.LocalPlayer
    local mouse = plr:GetMouse()
    local target = mouse.Target
    if target.Name == "Well Water" then
        local fishray = Ray.new(handle.Position,(handle.CFrame.p - mouse.Hit.p).unit * 100)
        local part, position = workspace:FindPartOnRay(fishray, plr.Character)
        if part and part.Name == ("Well Water") then
            print "success"
        end
    end
end)
