Materials and Preparation
Preparation required before the session:
Before the session begins, you will need to:
- Grate or dice an uncooked potato into small pieces (smaller is better)
- You won’t need more than ~3 tbsp of finely chopped potatoes
- Crush one chewable vitamin C tablet (or use vitamin C powder instead)
- Print out this table and graph, or copy them down by hand onto a sheet of paper
Materials needed during the session:
- Your potato, vitamin C, and sheet of paper, prepared according to the instructions above
- A 1 tsp measuring spoon
- 100 mL or more of hydrogen peroxide (concentration of 3% or higher)
- 3 clear cups or glasses of equal size (narrower is better)
- Lemon juice
- Alternatively, you can use vinegar
- A ruler
- Writing utensil
