Yeah... I'm 31 years old and I still love playing in sandboxes. But seriously, who doesn't? If you don't enjoy the feeling of digging out trenches and piling up sand into castles and fortresses then there is something fundamentally wrong with you and we can't be friends.
I also happen to be lucky enough to have a job where playing in the sand is actually a legitimate work activity. Yesterday a colleague (Darryl) and I spent an hour or more just trying to get the mixture for our sandbox just right. We basically invented the "Research and Development" department for the Penticton Museum right then and there. We decided that plain, dry, clean sand was not going to be interesting enough for our augmented reality sandbox, because it doesn't hold its form very well unless you add water, and that's not really an option for a museum - too messy, too much maintenance, and potential disaster if it ever leaked.
Luckily Pinterest provided quite a few options for DIY sand recipes.
Our favourite mix held together well but crumbled to resemble dry sand when crushed, it was strong but not too stiff. Here's the recipe:
- 9 parts sand
- 9 parts flour
- 1 parts mineral or baby oil (depending on how much you want to smell like an infant)
Mix well and play. It stays together unless you apply outside pressure, you can easily form peaks and valleys and even sheer cliffs. It makes your hands feel great after, too. Exfoliates and moisturizes.
