Book 27, Question 126
What are the safety rules for growing crystals at home?
Grown-ups should handle all hot water, since hot liquids can burn.
Use only safe ingredients such as table salt, sugar, and Epsom salt, and never taste your experiments. Wear safety glasses if a grown-up says to, keep jars away from little children and pets, and label everything. Wipe spills right away and wash your hands afterward. Good scientists always plan for safety first.
