What I enjoy doing more than anything is I have my little antique car collection and when the weather is pretty I like to get out one of my old cars. I have a little route I run down in the country down Nachez Trace Parkway. The loop down through there is just really relaxing not much traffic.
Of course not everybody's willing to go out and do the experiments but for the people who are willing to go out and do that - if the experiments don't work then it means it's not science.
