So how exactly do you fool an egg thief so thoroughly? Thank a material called Ninja Flex, which has a squishiness that approximates that of a sea turtle egg. By loading Ninja Flex into a 3D printer, Williams-Guillen could build an egg case that was flexible, yet strong. “After many iterations, we were able to get to something that really feels reasonably like a turtle egg and looks like a turtle egg,” says Williams-Guillen.
