So, I found this idea in a craft book for preschoolers. I was beyond excited to make this with them because I knew they'd like taking it home. However, when I did my test run I could not get the sailboat to stay upright at all. It kept tipping to one side regardless of what I did.
I went home, tried a few different things and finally found something that worked. Instead of using a magnet and a straw, I used two magnets and two paper clips. Now, even after shaking the jar my boat continues to readjust and float perfectly back up.
