Alien: Covenant may not have been the movie that everyone wanted but, at the very least, Ridley Scott kept up his long tradition of working with practical effects. A new, behind-the-scenes featurette shows part of the process for making the ooey-gooey xenomorph eggs in Alien: Covenant.

The video below shows creature effects supervisor Adam Johansen and others making and tweaking some of the props that have become iconic symbols of terror in the Alien film franchise.

The full featurette is on the home video release of Alien: Covenant, which hits shelves today.
