I have my particles labeled particle1 and particle2 (I will make more) I have tried this
script.Parent.Touched:connect(function(hit)
if hit.Parent:FindFirstChild('Humanoid') then
Game.Workspace.Particle1:Clone().Parent = hit.Parent.HumanoidRootPart
end
end)

Fixed code block
Can you please explain your problem further? From what it appears, it should work correctly.
I suggest you use workspace instead of Game.Workspace.
