I really want to break my wrist so I can get a cast, it is for a good reason that you don't need to know. So could someone give me ideas on how to break my wrist? Thanks!

You can find the materials to make a cast substitute at Home Depot. I would try making a cast.

I know you said you don't want to go into the details of why you need to break your wrist, but surely SURELY there must be a better way to deal with whatever situation you're facing without doing potentially permanent damage to a part of your body that you'll find pretty useful throughout your life!!!

As Ray mentioned, breaking a wrist is no fun. Just Google image search "broken wrist". It's not all pictures of quirky casts that all your friends get to sign. It's a pretty painful injury that could affect the use of your hands for the rest of your life, not to mention what would happen if you ended up impacting on blood flow or damaging nerves...

My girlfriend broke her ankle slipping down some stairs years ago, and she has problems with it to this day. It hurts when it's cold outside, she still can't run on it properly...

I'm sorry but it's a dumb idea. And the only reason I haven't moderated your question is because I hope that anyone else that's in the same frame of mind as you might stumble upon these answers and think twice before injuring themselves!
