Diatom cup coasters are designed to be highly absorbent and dry quickly thanks to the unique diatom material. What's so special about it? Well, let's break it down into simpler terms.

 

First of all, coasters are made of diatomaceous earth and have a sponge-like structure. This means that it absorbs moisture instantly. This material has lots of tiny pores, creating more space to trap and absorb water molecules, making it very clean.

 

But that's not all. Diatomaceous earth also has a very special mechanism called capillary action. Basically, it absorbs liquid against gravity. Therefore, when you place a cup or spill water on a coaster, the water is absorbed using capillary action and is stored in your pores. It's like magic!
