at first when you all started saying what else you guys used, my first reaction was, do they think my idea isn't good (you have to understand I am THE MOST sensitive and paranoid person ever created lol)
Then I realized something- you are sharing your ideas to help make it the best project ever. I now am going to make some, and I am going to try all of your ideas: the glycerine, the syrup, and the baby oil. If any of these help the glitter stay colored without changing the water, that would be awesome.
Please don't take offense to what I have said, I mean it as a compliment. You guys are awesome, and if you have any other ways of doing this, please share them!! That is what makes bbs so awesome!!!
