What can I do to help deter my 17 month old's throwing habits?

My little girl likes to throw her food. Which I know is what babies do. However, hers involves sippy cups and utensils. I happened to be on the receiving end of a fork the other day. Thankfully, I dodged in time. It was a fork designed specifically for toddlers. She doesn't do this out of anger or frustration. She finds it funny. I, of coarse, don't. I've tried everything from firmly saying No! and spats on the hand. Which I am not very comfortable doing. I'm just desperate because it's getting to where we can't take her out to eat. Any suggestions will be welcome. Thanks!
