of this ERD is to create a cheap alternative for stain removers in the field of Engineering. The main contaminant we will focus on is grease or oil which is common in machines as a lubricant. The group will focus on using Sodium Bicarbonate or Baking Soda and Oyster. Both of these materials have proven to be effective stain removers with vinegar being 8% acetic acid diluted in water. The group plans on mixing the two ingredients to create a cleaning agent capable of removing grease or oil stains

and ounces. Many other units exist. The equation for baking soda and vinegar is CH3 COOH + Na HCO3 -> CH3 COONa + H2CO3 . This equation effects pressure and volume by rising the temperature and wanting to get out of the object. The researchers hypothesis is that when the volume decreases the temperature rises and the object inflates because it wants more space. II. Materials Baking soda Vinegar Zip lock bag String III
