Make your own toothpaste

In school we did make things like toothpaste and shampoo but I never dared to use it. Who knows the amount of an ingredient might have been too much and ruins your teeth or hair. :D One time we went to this company called Shell. I think you know what company that is. They produce gasoline and products like that. We had a guided tour and were told about the history of Shell and what they currently do. We were also allowed to silver a jar using insanely biting materials. It was absolutely crazy, we had guards constantly watching us so that we wouldn't steal anything. You know if you steel the acids and have it researched you can be abso-bloody-lutely rich. Have an ugly platter, just put some acid on it and it turns into silver. Absolutely fantastic experience we had. It didn't make me decide to study in the direction of chemical industry.
