local ball = script.Parent

local debounce = false

function grab(hit)
	if debounce == false then
		debounce = true
		local x = hit.Parent:FindFirstChild("Torso")
		if x then
				local weld = Instance.new("Weld", hit.Parent)
				weld.Part0 = x
				weld.Part1 = ball
				weld.C1 = CFrame.new(0, 1, 0)
				wait(2)
				debounce = false
				end
			end
		end
