Weird baking question

Just saw something about using a marble in cupcake Tins to make a heart shaped cupcake... Only I don't have any marbles. What else is small and round or close to round and can go in the oven without being destroyed? Help me brainstorm!

a coin?

balls of tinfoil

That's what I was thinking but in the baking process the cupcake would just rise over it and it would just make odd shaped cupcakes... Maybe a stack of coins?
