.Safety
first
1. Work microscale (small materials, small amount of substances). 2. Work in a tray, ALWAYS use it. 3. ampoules Label first fill later 4. Syringes only from a pharmacy. 5. Even a candle burner must be used inside a tray. 6. Bind long hairs together. 7. Extinguish burners immediately after use. 8. Wear googles for chemical experiments. 9. Carefully wash your hands after experimentation. 10. Do not eat during experimentation. Experiments
