Self control: marshmallow and cake test

                                        Self-control

Try not to eat the marshmallow or cake for five minutes.

If you have wait for five minutes and you didn't eat the marshmallow, you get two marshmallows.

If you ate the marshmallow, you will not get two marshmallows.

If you did actually ate a little bit of a cake and the actor ask you if you did eat the cake, and if you said no, that means you are lying.

Do not leave the room when you are waiting.
