Technologies in the Film

In the future, a mini dehydrated pizza is stuck into a hydrator and in seconds an instant pizza comes out. While we are not quite at that level, there are machines that can dehydrate your food to prevent it from going bad quite as fast [1]. These food dehydrators are readily available, but in order to rehydrate them, you have to do it yourself by mixing it back with water. Its typically only done with vegetables.  Other than this, the food hydrator in the movie shown in the movie is fictional for the time being.
