The narrator suggests that the four boys wish they weren't there and want to forget what happned. These boys are probably ashamed to say they were and regret seeing Simon die. They could also feel guilty that they could not Simons death, so they wish to forget the savage way Simon died.
Pool Clarifiers â What are They? The most common type of pool clarifier chemical sold and used is known as a PolyDADMAC, an ammonium chloride with a highly positive charge density. Different concentrations of 10% to 40% are useful for nearly any negatively charged colloidal particles.
Wood, hair and rubber are natural polymers, but scientists have imitated these natural polymers in synthetic polymers that have many uses in the modern world. Synthetic polymers were first used as a water clarifier in 1945, but it wasn't until about 1970 that they were first introduced in the pool industry. The key to understanding why they work as a water clarifier is that each link in the polymeric chain takes on an electrical charge.
