Benjamin Davis from dv8 Youth Ministries in Crowley, TX brings us these super lightweight and simple light boxes.
They accomplished this design with air filters, duct tape, and some LED lighting.
Benjamin bought 76 air filters ($1.30 each). Then he bought 12 rolls of duct tape ($3.40 each). Total cost: $140.
First he took four filters and taped them together. Then he cut 6.5″ squares from the cardboard boxes the air filters came in. He cut those in triangles to use at the corners of his boxes to support the shape and block light. Then he taped the triangles to the corners on top and bottom of the boxes.
Finally he taped the boxes together to create a stack. He taped an air filter on the top box to keep light from escaping too much. Then he put an LED light at the bottom of each stack to illuminate it.
