Sealed Bag – Now, turn on the water spigot again and fill a sandwich sack with water. Seal it up. Ensure you have the seal fixed immovably. In the event that you stick a sharp protest through the water-filled sack, completely through and out the opposite side, you'll get a release, right.

The honed pencils slip between the atom strands without tearing the whole sack. Trust it or not, the long chains of atoms seal back around the pencil to avert releases." Steve's words
