Super cool experiment to make an egg stand up straight. 🥚First I asked the boys to try to get the egg to stand up straight. They, of course, couldn’t do it. Then I added a small amount of salt to each paper and asked them to try again. They were amazed the egg would now stand up straight! They then blew away the excess salt and the egg continued to stand. (Note: I used colored paper so they could see the salt, not necessary for the experiment.) Ideal for kids age 4-8.
