Fellow scientists,

today I come to you with an age old question. Since the first time a watermelon was cultivated man thought to himself: Can I destroy it with my penis?

That is why I ask for help, especially from all physicians, biologists, physicists and medical engineers:

Can a man do it? If yes how? If not why not and how can we advance the body to be able to achieve the goal? How much does girth and length matter? Is there an optimal movement pattern to break the melon? Does one have to reinforce it beforehand to prevent injuries or is this a matter of training?

I conducted some thought experiments but I am uncertain weather a long penis is more useful than a short penis. A long penis can use centripetal force. But a shorter one should provide more sturdiness.

Due to my lack of medical experience I can not tell if the average penis can be hard enough to penetrate the outer shell without major damage.

I am looking forward to reading your insights.
