Silica gel packets: surprising uses to protect shoes and gadgets
Those little packets that come in new shoes and gadgets are called silica gel packets.
They are filled with tiny beads that soak up water from the air.
That is why they help keep things dry.
If you put them inside shoes or bags, they can stop them from smelling musty.
They can also help protect cameras and other electronics from moisture damage.
People use them in boxes to keep papers, photos and stamps safe.
They even help stop metal tools from getting rusty.
You can also use them to dry flowers for craft projects.
They are not poisonous, but small children and pets should not swallow them because they are a choking hazard.
After a while, they soak up so much water that they stop working, and you need new ones.
Silica gel packets absorb moisture and can keep shoes, gym bags and handbags drier and less musty, especially in humid weather.
Placing packets in camera bags, electronics boxes and drawers helps protect moisture-sensitive electronics.
A few packets in storage boxes can help reduce moisture around documents, photographs, stamps and other collectibles.
Keeping silica gel in toolboxes or drawers can reduce humidity and slow rust and corrosion of metal objects.
Silica gel is generally non-toxic but poses a choking hazard to children and pets, and stops working once saturated with moisture.
