Humans have a knack for making messes.

No, I’m not just referring to toddlers who get their hands too sticky or roll around in dirt when their parents aren’t looking.

Adults have been known to make some pretty messy mistakes, too, like inadvertently spilling glasses of red wine on wedding dresses or scattering their children’s toys on the carpet.

Although accidents can happen to anyone at any time, you can avoid them by a putting a few simple precautions into place. And who knew that in the process, you could have a bit of fun?

Check out the directions and instructional video below to learn how to make your very own spill-proof party cup! Tote this “adult sippy cup” around instead of an open beverage, and never scrub stains out of carpets or clothing again.

And what’s more, you will love using a bendy straw to sip your drink from a stylish mason jar! How else would you decorate your special cup?
