Where to get silica gel

The gel itself is basically a mix of water and silica, the main component of sand. Together, the ingredients create pellets that, when examined closely, are made of molecular nets and have almost spongelike structure. All the tiny gaps among and between these molecules are what allows the gel to hold onto water so well. Water from moist air condenses onto the solid parts of silica gel.

The droplets accumulate and slowly build up enough to make contact with growing moisture deposits on nearby gel molecules. Eventually, the two merge.

Heat is strong enough to break the relatively weak bonds between the silica gel and water, and lets moisture evaporate out. If these moisture-sucking additives do their job while the devices are off, then maybe the heat the technology generates while powered on can remove the moisture the desiccants soaked up and keep them working for longer, the team reasoned. Silica gels might not respond best to heat from an electronic device, they found, but other desiccants might pull this trick off.

Researchers are constantly experimenting with silica gel packets and other desiccants to see what the materials can accomplish. A team of microbiologists, for example, tucked samples of the Streptococcus pneumoniae bacteria into individual packets and found that silica gel did a good job of keeping the potential pathogen alive during transit between labs. Researchers are happy to rework the silica format, too.
