what i did today


experiment 1: to produce oxygen

pour about a centimetre of hydrogen peroxide into the bottom of a small glass flask. add a teaspoon of rice vinegar and swirl. now add a few potassium permanganate crystals and the glass mists over. insert a glowing splint and watch it flare!


experiment 2: to produce hydrogen

put little rolls of aluminum foil at the bottom of a bottle. fill the bottle up with sodium hydroxide, remembering to place the bottle in a basin of cold water when you do this, because this is an exothermic reaction. put a balloon over the bottle neck and watch it swell with hydrogen and reach skyward!.
