Liquid Glass Spray was a spray made of sand and water. It could keep bacteria at bay.
Bacteria had been a problem since the evolution of multi-celled life. Penicillin, the first antibiotic, was discovered in 1928. Since then, more and more antibiotics had been discovered. Antibiotics were being used to kill bacteria. Unfortunately, they could not all of the bacteria. Only 99 percent could be killed. The 1 percent left was often the strongest. Soon, bacteria were developing resistance to antibiotics. A new solution needed to be found. A new concept was discovered that could prevent bacteria from gaining a foothold: Liquid Glass Spray.

Liquid Glass Spray was invented by a German company known as Nanopool. It was a mixture of sand and water. If coated on a surface, there would be a layer 100 nanometers thick. That was 500 times smaller than a human hair. It was flexible and even breathable. It allowed air to pass through. It was water-resistant and formed a barrier that was effective against dirt, bacteria, acid, heat, and UV light. Because bacteria found it almost impossible to replicate, disinfectants became obsolete. When applied to buildings, liquid glass spray could protect against water, heat, and UV light. When applied to the non-edible parts of food crops, liquid glass spray repelled insects and increased resistance to fungal disease. Liquid Glass Spray was not the only solution to the problem of bacteria. There was another: Sharklet.
