When hurricane Florence passed through in 2018, I pulled out my “Storm Box” and inside happened to be several Halloween glow sticks that were at least three years old. To my great surprise, they made perfect “nightlights” throughout the house during the days without power.
The package said they “last up to 12 hours” and they did, even after several years. They were especially handy for small children who could carry around their own little lamp. Now, I take advantage of every Halloween season to restock my “Storm Box”. Liane
