Copper sulfate crystals are among the most beautiful crystals you can grow, but you might not have access to a chemistry lab or want to order the copper sulfate from a chemical supply company. That's okay, because you can make copper sulfate yourself using readily-available materials. Materials for Making Copper Sulfate There are actually a few different ways you can make copper sulfate yourself. This method relies on a little electrochemistry to get the job done. You will need:

Answer: Both baking soda and baking powder are leavening agents, which means they are added to baked goods before cooking to produce carbon dioxide and cause them to 'rise'. Baking powder contains baking soda, but the two substances are used under different conditions. Baking Soda Baking soda is pure sodium bicarbonate. When baking soda is combined with moisture and an acidic ingredient (e.g., yogurt, chocolate, buttermilk, honey), the resulting chemical reaction produces bubbles of carbon dioxide that expand under oven temperatures, causing baked goods to rise. The reaction begins immediately upon mixing the ingredients, so you need to bake recipes which call for baking soda immediately, or else they will fall flat!

Did you know you can get a condition called "popcorn lung" from breathing the artificial butter flavoring from microwave popcorn? The artificial butter flavoring is a naturally-occurring chemical called diacetyl. Diacetyl causes no problems in the butter, milk, cheese, beer, and wine where it's found, but when vaporized it can cause damage to the bronchioles in the lungs, eventually deteriorating them into the serious irreversible condition called bronchiolitis obliterans. If you nuke a bag of popcorn every now and then, it's not a health concern for you, but workers in the factories producing the butter-flavored popcorn are at risk for lung damage, as are consumers who pop a couple of bags of corn daily. I would guess theater concession stand employees would also fall into this category.
