DIY Air Freshener lid for 8oz Ball quilted crystal jelly jars

thingiverse

There are several names for a product, including water marbles, crystal mud, and others. These tiny polymer beads, smaller than a BB, expand around ten times their size when submerged in water over time. As the water evaporates, they shrink again but it may take weeks or even months. Some people use these beads with scented water that contains soluble fragrances as air fresheners. I decided to try this out and created a lid system that allows for adjustable fragrance openings.
