how do i make flour into fake cement type sand?


im making a mini vacation sandbox like this https://www.instructables.com/id/Mini-Vacation-Sandbox/ with my daughter.... we dont have any sand on hand but we do have brown flour.it is midnight right now... i want the "sand" to be stationary as in never move from the place i put it. with shells on top. in past experiance pouring elmers into sand in great quantities the glue did not dry. the "sand" would be about 1/4 in deep. how do i go about turning this wheat flour into something more permanent?

You might try an aerosol spray-on adhesive like is used for mounting posters or photos. You might also experiment with hairspray.
