Use in silica gel packs
Have you noticed that your Halloween figurine softens after a few days? Throw a flint or two at it and your neighbors will enjoy it for a long time!
Do you have a big bag of dry pet food? Stick the silicone bag on the side of the bag to make it last longer.
One thing I’ve been struggling with this winter is condensation on the windows of the house. Keep a packet of silica gel near a window. This will also work for foggy car windshields.
