How do you do it? The only way I can think of is to spread it out in the sun in small quantities/thin layers to dry thoroughly, but between grey, drizzly days, wind that will blow it away if the tray isn't deep enough, and how long it will take to dry out a good amount of sand, I can't help feeling that there's a better method that my brain isn't bright enough to think of. I have two or three baking trays I could use, but they're not large, some would blow away, and it will take me forever to get the whole bucket full of sand dry. Halp.
