I wasted my allowance on that one, and others
One I didn't fall for was the "Make a ghost" which consisted of a balloon you had to fill with helium and the drape the 6"x6" sheet white of white fabric over it - Voila!"
I remember all of those except the Bear/Bare one.
I actually ordered a telescope from a comic book when I was around 11. I earned the money picking cotton. I sent my $3 (?) off to some company in Miami and maybe a week later actually received a pretty nice little pocket telescope. It also came with a pigskin case lined with velvet.
I found an old pair of glasses back when I was in the seventh grade.
I told everyone they were a pair of those x-ray glasses.
I’d look a girl up and down and go,
“Oh, yeah....nice.”
Had to go see the Principal and apologize to all the girls.
