FOR THOSE WHO DIDNT TAKE CHEMISTRY IN SCHOOL, BUT WANT TO MAKE A REAL GLIW STICK. HERE YA GO MATERIALS: (1) BOX OF BAKING SODA (1) BOTTLE OF DISTILLED WATER (1L) EQUIPMENT: (1) STAINLESS STEEL OR CAST-IRON POT (1) STAINLESS STEEL SPOON (1) SEALABLE PLASTIC OR GLASS BOTTLE (1) KITCHEN RANGE (gas ranges are preferable but an electric will do) (1) DUST MASK (optional but very highly recommended) (1) FUNNEL DO: -ADD 1 CUP BAKING SODA TO POT AND SPREAD INTO EVEN LAYER. -ON RANGE, ROAST BAKING SODA OVER MEDIUM-HIGH HEAT. -AS BAKING SODA BEGINS TO BUBBLE, USE SPOON TO GENTLY STIR. **AVOID CREATING A DUST CLOUD OVER YOUR ROASTING POT. A DUST MASK WILL NOT PROTECT YOUR EYES** -WHEN CONTENTS OF POT SHOW NO FURTHER SIGNS OF GAS EVOLUTION, REMOVE FROM HEAT AND ALLOW TO COOL. -ONCE SIDE OF ROASTING POT IS HOT TO TOUCH BUT NOT HOT ENOUGH TO BURN, RETURN TO LOW HEAT -VERY SLOWLY ADD DISTILLED WATER TO ROASTING POT WHILE STIRRING GENTLY UNTIL SODIUM CARBONATE IS COMPLETELY DISSOLVED OR YOU RUN OUT OF WATER. -REMOVE FROM HEAT, COVER AND ALLOW TO COOL -INSERT FUNNEL IN MOUTH OF SEALABLE GLASS OR PLASTIC BOTTLE AND POUR OFF LIQUID. -SEAL BOTTLE **WARNING: SODIUM HYDROXIDE WILL CAUSE SOME PLASTICS TO BECOME BRITTLE OVER TIME. ALWAYS WEAR GLOVES WHEN HANDLING AND KEEP AN EYEWASH BOTTLE FULL OF DILUTE VINEGAR HANDY.** You are now the proud owner of an extremely useful piece of data and a bottle of sodium hydroxide with a concentration > or = 95%. Try not to get it in your eyes.
