Here are some things from my backyard.
My Mom was visiting us, back before they got rid of pennies. We were looking at a penny from 1968 and there was discussion of how pennies used to have more copper in them. We wondered if an older penny would age differently outdoors, so we set up an experiment on the Buddha. They do age differently. Though my younger brother later remarked that we didn’t have controls and such that one should have in an experiment. He is a teacher.
At my dayjob, an award was mistakenly delivered to us. The supplier didn’t want it back, so I thought I would set it in the backyard and see what happened as it weathered. Not too much really. The points of the star fell off.
As Manien worked in the garden, she kept finding pieces of glass, so she collected them in these jars. The legend goes that there was a drunk who lived in the house back in the day, and he would hide his empties in the garden. There was also one wall that got opened up and was full of bottles he had deposited there.
