Cullens always has something interesting and I loved this piece of her imagination. See the video here to see how she made the binoculars.
I would probably add a transparent sheet either butter paper or a plastic bag cut into circles and stick them on one side of the binoculars to let them know that’s its glass that helps things appear closer. Just Cut the paper a size bigger than the circle of the binoculars and stick it overlapping on the binoculars.
This sounds fun. Thank you Cullens.
