Glow sticks last longer when stored in a Ziploc bag
We recently broke out a pack of glow sticks as evening entertainment for the kids. Our friend, a chemistry professor, suggested we put a few in a Ziploc bag in the freezer to see what would happen (a science experiment for the younger ones). The next day we took them out and hey presto, they were still glowing, unlike the ones left next to our beds all night.
