This is a handy tip if you ever puncture your radiator. If you happen to have one handy, you can crack an egg in it and the egg will solidify and plug the hole. It gives you a temporary fix to get somewhere and have it fixed for good.
Believe it or not, this can actually work. The only drawback is you need to have an egg handy. Hmmm...kind of makes you wonder what that breakfast omelet is doing to your insides!!
