Step One: Hold an adorable baby. It's better if it is someone else's so that you can keep your beach body.
Step Two: Crush ice. Display your fierce resourcefulness by using whatever means is available to you.

Step Five: Abandon the mess in the kitchen for a better time elsewhere. Surely that is someone else's job.
