okay, this is a reeally dumb science assignment, i need to make a procedure to preserve a pb and j sandwich i can use these materials: sheet of cardboard, string, straws, aluminum foil, plastic sandwich bag, sandwich, tasking tape, brown paper bagi really don't know anything about food preservation, so give me some tips please! what should i do./ make out of the materials i can use?????btw, this is from the time i pack it in the morning till noon, so like 4 hoursto preserve the identity of the sandwich
Put the sandwich in the baggiethen in the brown paper bag for packingThen cut and fold the cardboard to make a box just thr right size for the sandwichPold it up and tape it closed with the sandwich in itThe preservation here just means that it won't get all muched upand squished.
