Birthday
For this you would have to make a clown on a chart paper n leave its nose blank. Each child will be blind folded and would have to put a mark inside that nose with a red marker. The child who puts the mark perfectly on the clown's nose, wins.

Instead of the marker you can use things like- round shaped stickers, a small red ball with a double tape on its one end or a small inflated red balloon with a double tape on one end.
