OK I can't find bisodiumcarbonate ANYWHERE! :crazy: What the heck is it, and where do you buy it? The betaine or liquid surfactants seem hard to find too. Your piccies are gorgeous and I think I like the look of these bubble bars better than the recipe I have, but you have some wacky stuff in this recipe and I don't know where to find it. I'm sure it will be worth the wait, once I find a source.
