This is officially our first exhibition flair move - meaning this is NOT a move you can pick up a full bottle at work and give it a try. DO NOT do that. You'll spill everywhere. This is a move that should be done with a bottle that is no more than 1/4 full. As always, practice at home with an empty until you're comfortable with it. Then, try adding a couple ounces of water at a time and until you see how much is too much. I'll warn you ahead of time: you will get a bruise from practicing the bump. It just is. So practice for no more than 10-15 minutes at a time. Or until it gets too sore. And don't practice the day before you have a shoot for your job as a forearm model.
