I opened a pack of Clover Chip but suddenly had a change of mind. I wanted to eat other food instead. The crispiness of the chips will gone after awhile. Setting it aside was not a good idea.
I remembered we have a Homio semi vacuum food container. Storing the chip in it for a couple of hours might preserve its crispiness. I got the food bin. Placed the opened chip bag. Then pumped out some air.
After approximately four hours, I opened the food bin and ate the chips. It was still very crispy. No signs of toughness. The vacuum food bin is effective. I wonder if it can preserve chips for days or for weeks!
