In-a-pinch way to keep food fresh

“After making s’mores at a picnic, I realized I didn’t have a chip clip to keep the marshmallows from going stale. Then I remembered a trick my grandson taught me using straws. First fold the open end of the bag over a straw. Then grab another straw, cut it in half lengthwise and slide it over the first straw. This DIY clamp sealed the bag and kept our marshmallows fresh until our next cookout!”
