It´s easy. Take big leaf of paper, some kids, teens or adults, make a small hole and let them get thru. The result is really interesting.
(Every photos with holes in paper you can see in the collection Thru the paper
If it´s not enough, you can give them something into hands. For example music instruments.
And when is taking photos over, you can use the paper for lots of photos more. Especially kids are funny with the rests of paper.
