For a while when he was 2, whenever the rubber dishwashing gloves were within reach, my second son would grab one (and only one), put it on, and run around saying "I am Batman."

Anything arched or squared has time portal potential.

Sticks are fossils (okay, they aren't "household objects" except in our house where they are), and can be used to create entire skeletons.

One evening when he was 5, Batman bit a piece of salami into a particular shape, held it up proudly, and said "Look Mom! Dinosaur hips!" I'll give him credit --- he had formed it pretty accurately.
