Well, mythbusters do sometimes try to clone the myths to see if they really work or not. Once again, it is fun to watch. Sounds like you are being too serious. Life is short, have some fun.
Yes, Mythbusters is television. It's "fun to watch." That's exactly the problem. And yet people are acting like this is real science. Real science is not always fun. It's often very boring. Nobody wants to watch a show about that.
I have lots of fun. I just don't claim it to be science. And I don't defend people who put others at risk.

I haven't heard of parents filing for permits to fire cannons or renting them firing ranges. Interesting.
