make a tool not attached to the not hand?

I am making a basket ball and I have a animation of my right arm moving but the ball looks weird because the ball moves with the hand how would I make it to were the ball does not follow the hand but also in front of you?

this is what I think the script should look like

local offset1 = … local offset2 = … local alpha = 0 local goingUp

while true do Tool.GripPos = HumanoidRootPart.Position + offset1:Lerp(offset2 , alpha) - arm.Position if alpha == 0 then goingUp = false elseif alpha == 1 then goingUp = true end if goingUp then alpha = alpha - 0.01 else alpha = alpha + 0.01 end end
