In this experiment you fill a plastic bag with water and poke a pointed pencil right through it. And surprisingly, not a drop of water spills. You will need a good quality zip lock bag and a couple of sharpened pencils to do this experiment. Open the plastic and fill it to the brim with water. Then close the zip to lock the mouth of the bag. Now you are ready to do this amazing experiment. Poke a sharpened pencil right through the plastic bag filled with water. Surprisingly, not a single drop of water spills out. Why? The tear in the plastic shrinks and seals any crevice preventing any water from leaking. And then poke a second and the third pencil. Even after poking half a dozen pencils not a drop of water spills. This amazing experiment will make your friends wonder struck.
 
Finally, fill a large good quality plastic bag with water and poke a dozen pencils through the water bag without spilling a drop. This is a graphic and amazing experiment.
