The Invention of Toothpaste

This week we invented our own toothpaste! In our groups, we decided how much of each ingredient to put into our recipe:

  • Bicarbonate of Soda
  • Cornflour
  • Peppermint essence
  • Glycerine
  • Water


Once we had made our toothpaste, we tested it against 3 other brands of toothpaste by trying to remove a sharpie stain from a tile.
