Frozen Sponges
A sponge might not be an essential item on your packing list, but it can come in handy while traveling. No, we’re not suggesting that you bring one to clean your hotel bathroom. Instead, a sponge can help keep your food fresh during long journeys.
Generally, items that could potentially be used as a weapon (like gel packs or ice packs) are prohibited from passing through airport security. However, there is an easy way to ensure that you’re able to bring your delicious cheese on the plane with you.
