I had the best bath using Lush's Crackersnap ballistic! The scent is really citrus. It turns your water a gorgeous lime green colour. Some ingredients are: lemongrass oil, rosewood oil, popping candy & bergamot oil. What i really loved were the surprises you got inside. I got a joke, a party hat & a re-usable crocodile bubble bar. All in all i think this is a great idea It was £7.50, i brought mine from the Lush website. Unfortunately they were limited edition for Christmas, but i'm really hoping lush brings them back next year. Have you tried this ballistic? What do you think?
