Step 1. Go to the beach (or a zoo with seagulls) and bring some bread. Seagulls apparently like wheat bread. A lot.
Step 2. Set up a camera on a tripod (or set it somewhere stable). Hook up a remote. You may want to cover your camera with a shopping bag as seagulls poop a lot.
Step 3. Have one of your kids spread bread pieces all over in front of your camera. Manually focus on them while they're doing this.
Step 4. Walk away so that the seagulls will come closer to your camera. Unlike in the movies, seagulls really don't like people and they won't land on your arm when you hold it out.
Step 5. Wait for the seagulls to come. Take advantage of the time you're sharing with your kids to talk about life.
One seagull is always the first and the bravest. Once the brave seagull comes and takes a piece of bread, it's on like Donkey Kong. Its like seagull popcorn.
Step 6. Take a bunch of photos with your remote and then show your kids!
*note: some people have said that bread isn't good for seagulls. Don't worry about that, there are plenty of them.
