Very cool! Let us know how they worked.
I stumbled upon a website that stated if the used lids are boiled in water and baking soda for 15 minutes or so they can be reused. I have done this with success; the lids held the vacuum. I try to be very careful when I open a jar so as not to damage the lid and before I attempted this, I inspected the gasket to look for any signs of extreme wear. I've only tried this with lids that have been used once. I imagine as time goes on, this trick won't work anymore.
