chemistry experiments for children

Keep glass apparatus spotlessly clean. Contamination often spoils the
results of experiments. When you wet clean glass, it takes on an evencoatingof
water, but on dirty glass the water forms smalldropletsinstead. You can use
any gooddetergentfor cleaning, but be sure to rinse theapparatusthoroughly
afterward.
