Sea turtle eggs can float in the air

*Well i am in creative mode, then i put some turtle eggs on a sand. I want to destroy the egg, but i destroy the sand. But the egg didn't break, it's flying. Im checking again with making a sand tower with a torch beneath it, then i put an egg in top of it. When i destroy the sand tower, the egg is still there, flying in the sky. Please fix this, it's weird.
