So cute! Imagine these in the middle of your bath bomb. Cute little eggs that measure 2 x 3 cm. You soak the egg in water, it hatches a dinosaur and then you let the dinosaur sit in water, and it grows. How awesome is that?
A: The actual hatching eggs are inside a shell already. They need to be immersed in water to dissolve the shell and for the dino inside to grow. There is not enough moisture in your BB to activate them, as they take 48 - 72 hours to dissolve fully immersed in water.
