Absolutely love this idea!  Thank you for sharing.  I especially like the peel and stick feature.  So, are you thinking a strip filled with absorbent moisture crystals with an adhesive backing?   Or???  Any sketch you can share with us? 

We like your idea so much that we marked it as our favorite of the week (see the front page at www.cloroxconnects.com under my favorite ideas this week and to see it highlighted).
