Costco will sell you a huge bag of baking soda. $10 for 13 pounds.

You can use it for experiments on weeds you hate as it is quite hard on plant life. You can use it to put out fires. You can mix it with vinegar (also CHEAP at Costco). This is stuff you need, as much as Mentos and Diet Coke, also available at Costco.
