There is an Elmer's Glue commercial on tv, and at the end they have a 1-800 number that flashes up for like 10 seconds with no explanation as to why, it just says you must be 18 to call. I called (undying curiosity you know, lol!) and it is for a free project book and includes valuable coupons. Here is the number!
1-800-376-1523

Hope this helps, and if you get a book, please post what is inside, I am dying to know and hope it arrives before Target clearances their school supplies!
