Is an Index Card Stronger than Water?

Is an Index Card Stronger than Water?

Fill a small cup about one-third full of water.
Place an index card over the cup so that it covers the entire top of the cup.
Hold the index card tightly onto the cup, then carefully turn the cup over.Some water might leak out at first, but the index card will hold the rest of the water in!
