Hi bombdiggybabe, I too have been trying to get the spinning, floating, colorful bath bomb like L*ush. I've tried for about a year now with a ton of different recipes and while my bath bombs are good...they just arent as good as lush. Ive tried upping the citric, but they didnt seem to help. I can get mine to float and color the water but i cant get them to spin. Sorry i couldnt be of more help. If you ever find a solution, I would love to know!
