How many times have you given something fresh to your children for lunch only for them to open the lunchbox at lunch time and to find that the freshness has gone and that the warm weather has spoiled the food? This is a major source or worry for almost every mom as they come to grip with the fact that their son may not always be having a fresh lunch at school or anywhere outside.
What can be done here is to use a hack for an icepack. One such hack is to put a sponge inside the freezer and then place it inside the lunch box when it is frozen. This would ensure that there is a cold source available to counter the impact of the warm weather and to keep the food fresh at all times.
