Polymer, actually, so it's every single grain of sand is coated in plastic.

Not real ideal for the classroom I work in then.

"Sorry Mom, but somehow your son ingested plastic coated sand. Yes, I'm quite sure he needs to go to a hospital right away."

I see what you did there.

Can't wait to chomp down on some of that sweet sand! I mean I've had it with the traditional sand chock-full of gluten. That stuff isn't good for you.

My sister in law is allergic to gluten, and she swears that she can get sick just from handling stuff with gluten in it. I'm not totally convinced, but if people believe it, I can understand why they'd market it that way.

Where I live, teachers are still debating whether or not to ban wi-fi from schools because of, I don't know, radio sickness or some shit.
