Burying your popsicles in an ice-filled cooler. Since cold air sinks, the bottom of the cooler will be the coldest spot inside, which will safely store popsicles.

Simply make a base layer of ice at the cooler's bottom, then place the popsicles flat on the ice without overlapping. Finally, add more ice until they're completely covered.

Use a thermos as an extra layer of insulation to keep the popsicles frozen in the cooler. First, place the popsicles in the thermos, then add ice inside it.

Now, place the thermos cap and toss the thermos into an ice-filled cooler with the rest of the food. In a pinch, you can also use the tumbler from

an ice cream maker for this hack.

This trick takes a little planning

but not a lot of leg work. The night before your picnic, place your cooler in a room-temperature

spot and fill it with ice.

The next day, pour out any accumulated water and refill it with more ice. The cooler will stay cold longer, and your popsicles should remain frozen until you're ready to eat them.
