The juice is on the loose!
There are all kind of fancy gizmos designed to get the juice out of citrus including one that looks like a giant garlic press. It works fine, but you've gotta be strong.
Nothing works better for me than an old fashioned juicer with a little built-in bowl and a strainer like grandma used. I bought a nice glass one at an antique store.
