NOTE: This video has been re-uploaded because I made an error in the last one. I said ashes have sodium hydroxide in them, when they really have potassium carbonate, which is converted to potassium hydroxide by treatment with calcium hydroxide or oxide. I hate having to reupload, but the error was too big for me to let go. I do not like the idea of spreading misinformation. I hope you guys can understand!
