The Crafty Chica has instructions for making these cute bath fizzy “cupcakes.” These would be adorable with black or scarlet icing and little sugar skulls on top.

A couple of notes:

• Her recipe calls for grapeseed oil, but any skin-soothing oil will work (we use sweet almond oil in our skull fizzies).
• I’m not sure about the whole meringue-frosting thing; I’d be tempted to use something like a tub truffle mixture instead.
• If you don’t have a silicon cupcake mold handy, stack a few foil or paper cupcake liners together for extra stiffness. I think I’d prefer to leave the liner on anyway, for decoration. (Use spooky ones like this or this.)
• Be really, really careful about moisture. The fizziness is activated when the baking soda can interact freely with the citric acid. Too much moisture in the mixing stage will leave you with a bubbly mess. Likewise, make sure you store these in a dry place.

Individual fizzies would make unusual party favors, and a set of four in a nice cupcake box would be a lovely hostesss gift. They’re fast and easy to make, so do give them a try.
