Here's a fun, science activity you can do that will make your kids giggle and make your whole kitchen smell like soap. Simple enough, put a bar of Ivory soap in a microwave on high for about two minutes. You can see results in just a few seconds so if you wanted to put it in for only one minute you would be fine.

Another benefit is it makes your whole kitchen smell like soap so people will have the impression that you cleaned! Or maybe they'll think you took a bath in the sink, who knows.
