while(wait())do
script.Parent.CFramePart.CFrame = script.Parent.CFramePart.CFrame * CFrame.Angles(0, math.rad(-1), 0) -- Here are your rads
script.Parent.MiniTsunamis:SetPrimaryPartCFrame(script.Parent.CFramePart.CFrame)
end
I don't know how to fix it!

I may not be correct, but try using FromEulerAngels, it rotates on its self.
Make sure the primarypart is in the center also!!!
