This is a product that I discovered last ISM in Cologne /Germany.
It is gum in powder form, which ressembles sand. It is intended for the children to play with it and form sand castles (which eventually can be eated becasue the product is bubble gum).
It is produced by the mexican company PISSA. I already wrote about them in the past because they are specialized increating funny products. In fact, their brand DELICREA covers a range of special products with the “fun” dimension. Thier motto is “edible toys”, and they have, besides “Yummy Sand”, also “Emotipaint”, “Lollipop maker”, “Candy dough” and “Candy bricks”. Check their website for more info: www.delicreacandy.com There is even a video about this novelty.
