The answer is no. This image seems too good to be true, but this experiment is completely possible. The reason the pencils are able to go through the plastic bag without leaking is because of the material of the Ziploc bag. The plastic baggie is made up of polymers which are long chains of molecules that are flexible. When the pencil is pokes through the bag, it slips in between the chain of molecules. They then make a seal around the pencil which ensures that water will not leak out.
