Also, does it change colour to indicate it needs a re-charge so to speak?
I've bought some self indicating silica gel beads (Silica Gel Dessicant Granules Beads Self Indicating Loose Multilisting | eBay) recently, and intend to use it in a suitable container once I find one (there are many lone socks around the house which are suddenly screaming out at me to be used!)
