I used to love playing these computer games as a small child and how animals like in the video the crabs can regenerate. Its basically a healing process that allows the re-growth of body part.
if we were able to "mimic" items such as plastic with the same cells as planaria or other like species. we can use the items and if they break, place them in salt water for about a week (think fish tank). and take it out and the item should have re-grown back together.
