Tweening a handle doesen't work?

So whenever i try to tween a handle to put in a tool..... the handle just falls out of the players hand whenever the tween animation runs and then after that the tool deletes itself. Is there anyway to make the tool not fall out out of the players hand and to make it not delete itself?

Tween script:

local TweenService = game:GetService("TweenService")

local part = script.Parent

 

local Info = TweenInfo.new(

3, -- Length

Enum.EasingStyle.Quart, -- Easing Style

Enum.EasingDirection.Out, -- Easing Direction

0, -- Times repeated

false, -- Reverse

1 -- Delay

)

 

local Goals =

{

Transparency = 1;

Size = Vector3.new(15,15,15);

}

 

local tween = TweenService:Create(part,Info,Goals)

 
wait(3)
tween:Play()
