How do I make players slip off each-others heads?

I am now using ZonePlus, but it is still very dodgy:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Modules = ReplicatedStorage:WaitForChild("Storage"):WaitForChild("Modules")
local ZonePlus = require(Modules:WaitForChild("Zone"))


local Part = script.Parent.Parent
local Zone = ZonePlus.new(Part)

Zone.itemEntered:Connect(function(Item)
	if Item.Name == "Left Leg" then
		print("Left Leg en")
		Part.Velocity = Part.CFrame.LookVector *-12
	elseif Item.Name == "Right Leg" then
		print("Right Leg en")
		Part.Velocity = Part.CFrame.LookVector *-12
	end
end)

Zone.itemExited:Connect(function(Item)
	if Item.Name == "Left Leg" then
		--Part.Velocity = Vector3.new(0,0,0)
	elseif Item.Name == "Right Leg" then
		--Part.Velocity = Vector3.new(0,0,0)
	end
end)
