The effect is very visual, and easy to get right in a few minutes.
But my goodness, can we
stop with the lying in ads?
NO TAPE OR ANY OTHER STICKY STUFF
This is printed in
bold in the ad copy, and it's 100% false. This effect is impossible without using sticky stuff,
which is PROVIDED in the box. I would have bought it either way, but the dishonest lying is
disappointing and getting old.
