You'll never get one to do it voluntarily.
Ha it's not new idea and yes morons have done similar things to prove their faith.
I am just saying to shut up the christian argument challenge them to something they know is BS to prove their faith. If they don't take the challenge hold it over there heads till they do it also when they fail it. This is much like when Christians try to get atheist with their challenges of reading the bible or having faith. Basically prove the christian lacks faith as well.
