Eggs aren't just for eating: crushed egg shells keep slugs away from your plants while using egg membranes can help lift out stubborn splinters from your skin.
You can use egg membranes for splinters while crushed egg shells keep slugs away from your plants.
If you have a splinter you can't get out, break open an egg and retrieve the membrane that's around the inside of the shell. Put a little bit of this membrane over the splinter, and in six or seven hours the splinter will have come out enough that you can pull it out the rest of the way.
The biggest worry I have for my garden is that slugs are going to eat my vegetables before I do. Since I do not like to use chemicals in my garden, I use crushed egg shells to keep slugs away from my plants. I crunch up empty eggshells and sprinkle them around the edges of the garden. They are much too pointy and pokey for the slugs to get over!
