People worry that you can’t really teach your kids science without a school lab. Well, try these on for size;)!
You can simulate a white hole in your kitchen sink. Wired has a great article on not only how to do the white hole but a great break down of what it really is.
Then you can pop over to OrbitingFrog to read how to measure the speed of light. All you need is a microwave, a microwave safe square (or rectangle) dish and marshmallows or chocolate chips! It is an awesome experiment!
So go, learn and have fun with science!!!
