This might not be the right territory, but anyway....
I've been playing this simple game with my 3 year old. The aim is for one person to wait in a room or facing the corner without looking, while the other person hides the corn somewhere in the yard. When the corn is properly hidden, you can call out for the other to come find it.
We use a plastic one, but a real corn cob with the husk still on will also work. He asks to use other plastic toy food that we have, but I insist that it needs to be corn. It has a double meaning and I'm sure most stackers know what it is!
He can't help but to tell me where it is, so I need to constantly keep reminding him not to tell me.
Its a fun game to play with young kids. Enjoy!
