Denmark may have the lockdown on Lego, but a neighboring country is also producing something children can use to build things: Sand. No ordinary sand, of course. A company called Delta of Sweden, which manufactures modeling compounds for use in the educational, medical, therapeutic and arts & crafts markets, has an invention called Deltasand. The stuff has been licensed by several toymakers, most notably Colorado-based WABA Fun, who have produced this video demonstrating the product (rebranded “Kinetic Sand“):

You probably noticed the video mentions the product is 98% sand, but neglects to tell you what the rest of it is—leading one cynical YouTube commenter to respond with “98% pure sand, 2% deadly chemical compounds.”
