Hey there Olivia!! Sorry it took me so long to respond, I've been covered in butters and powders and colorants...oh my!!! LOL...ok...I THINK I figured out the key to making them float, and it's really simple, actually....DRYING TIME!!!! That, AND the use of lighter oils...I LOVE my sinkers, don't get me wrong...they are pretty in the tub and super moisturizing with no ring of color and oil around the tub thanks to an emulsifier...but I wanted a few that were like some of the Lush bombs as well, and I knew I could do it. With my bedtime bomb, I made a blue core using 60 mm Christmas bulbs and a light oil, and very little kaolin in those. The first time I tried this, I used my "sinker" bomb recipe, with all the harder butters, and that defeated the purpose of what I was trying to do (duh lol). I also let them dry overnight, and tried to pack the purple/pink shell around it the next day. No dice. I also altered the recipe of the "shell" to be more like a bubble bar, adding less citric acid than the core and using slsa. Well, the end result was a floating bomb (I have to admit, had I let it dry longer, it would have floated the entire time) but it bobbed around the surface of the tub, and then blue shot out of the sides of the bomb!!! It felt so great to NOT want to get outta that water, with a bomb I made myself! OH!! One more thing, I DO use witch hazel to spritz, and I also didn't wait to pack the shell around the core of the bomb, I did it right away, and instead of using my stainless steel molds, I used the ones from Wholesale Supplies....worked like a charm!! I'm SUPER happy right now! P.S. I made 8 "cores", and was ready to start packing when my mother called, hence, I was hugely distracted and ended up with one bomb to test with

so in my experience, time is of the essence...I waited and the mixture wouldn't stick to the cores, but the first and only one came out amazing!
