After reading up on cellulose I realise that Im using a very small amount, I have still had some great bubbles but now mixing up with more cellulose and testing it all up again to see impact from baking powder, baking soda and citric acid.
It seems to be some different kind of cellulose, or maybe just the name so heres some picture of what Im using.
So its called wallpaper paste, made from high-density cellulose without any chemicals.
It´s like granulates or small flakes.
Maybe this makes some sense now. So if this is the same as others use then let me know.
