Making A Rubber Ball from Latex
Description: Liquid latex is made of very small globules of polymer hydrocarbons suspended in water. A small amount of dilute acid is added to the latex, neutralizing the ammonia which is added as a stabilizer. The irregular shaped globules join together in a random network to form rubber.
