I save all my glass jars

Use glass or plastic jars for storage of beans, nuts, candy, rice, small pasta and many other foods

Please do NOT throw away your mascara wands. Instead, clean JUST THE WAND with dawn soap, place them in a ziploc bag and mail them to a Wildlife Refuge accepting donations. These little wands are able to be upcycled to clean away oil, larvae, fly eggs, mites, infections, mud and other contaminants from wildlife. Works great for medical care and wound treatment

Pick your refuge to mail to:

Appalachian Wild
P.O. Box 1211
Skyland NC 28776

OR

Wildlife Wands
P.O. Box 1586
Southwick, MA 01077.

When I was in middle school, I made one of those stress-relief type "wave" moving liquid bottle things to mess around with , if anyone remembers those from the 1980s or 90s. Any bottle or jar that you can seal back up would work, I used a 2-liter soda bottle I believe. You fill it halfway with vegetable oil and most of the rest of the way with water mixed with food coloring to make it bright and contrast from the oil. I suppose you might need to leave a little air in the bottle, but perhaps not, hmm. But so the oil and water do not mix of course, and the idea is that the brightly colored (blue, say) water appears to be the only thing in the bottle when you move it around, and it is making waves and whatnot. That's a crappy description based on a 30-year-old memory, but I do remember they sold similar things in stores, and it was really fun to see the illusion of the water kind of defying physics and moving so calmly.
I am going to go try a miniature version of this, although I'm not sure my red food coloring will provide such a calming atmosphere. :)

Put all your decorative wine and other glass bottles filled with water on the window sill and let the sun heat up the water in the bottles and then the heat will radiate over night in the house to keep it warm.
