Well, I have finally gotten cloth wrapped around my rusty horseshoes and soaking in water and vinegar. I did another cloth with lots of found objects. For my third experiment I soaked my cloth in vinegar and water and climbed out on the roof. I wrapped it around an old antenna poll and then squished the cloth together. Finally I wrapped a plastic garbage bag around it and tied it with string. We are going to begone several days, so they will have several days to set up. I can’t wait to see them.
I wonder what my son will think when he sees the messy experiment in the bathtub and the bag wrap when he looks out the window. We will be gone before he gets home.
