All Bottled up: The Perfect Ecosystem

Scissors, glue, white copy paper. Procedure. Fold a sheet of white paper in half lengthwise, or “hotdog style” (see above); then, fold it in half from side to side, or “hamburger style,” twice. Unfold the last two folds; this will give you a total of four boxes (sheet is still folded in half length-wise, or “hotdog style”). ................
