Have you seen those weird melted cacti with holes in them around the slurries? Try putting ice on them. It gives you Aether, and in about 2 days you will get an ice flower from the cactus!
Note to @Emily_Purplebottle:
They fixed that problem. If you plant an ice flower in the incubator and then put ice on it, it will grow in a few days. Then, you can choose whether to harvest a snow-globe or a snow cone. If you put a beaker on the ready-to-be-harvested cactus, it gives you a snow-globe. If you put a can on it, you get a snow cone.
