Bake the Right Way: Baking seems like a relatively easy task. After all‚ you only have to buy a box of cake mix‚ blend in some extra ingredients‚ put the batter in a pan and throw it in the oven for a couple minutes then‚ voilà; you have a cake‚ right? Wrong. Baking is not something to be done by just any mother making a treat for their child’s school bake sale. It is an exact science that if done wrong‚ could potentially produce a burnt‚ tasteless‚ ugly‚ disastrous excuse for a cake that is as

Roasted Salt-and-Vinegar Potatoes From Cook’s Country | August/September 2012 Share Email Print Shopping list Add to favorites WHY THIS RECIPE WORKS: Cooking small red potatoes in a super-saturated salt solution creates an incredibly creamy‚ well-seasoned potato interior. After the potatoes are par cooked‚ we “smash” them to expose some of the potato flesh‚ brush them with malt vinegar‚ and roast them on a well-oiled sheet pan until the… read more Roasted Salt-and-Vinegar Potatoes Making crispy

In the third article “Australian State Bans Cosmetic Surgery For Teens”‚ written by Dan Childs. The text is pretty clear about its opinion on cosmetic surgery on teens. It wants to ban cosmetic surgery because teens are not able to make such a big decision‚ when there body is still changing. Further on there are also many risks that comes with these surgeries‚ for example death or a heart attack. There are also people who think that cosmetic surgery on teens shouldn’t be banned‚ because the government

SODA AND MENTOS Physical Science (3rd block) Mythbusters Project Introduction This experiment is to prove the theory that when Mentos is dropped into a bottle of soda the end result is a huge fountain spray of soda from the bottle due to a process called nucleation. Hypothesis If I drop Mentos candy into a bottle of soda‚ then it will create a huge fountain splash. Materials *Regular Mentos Candy (one)

VINEGAR (ACETIC ACID) AS ALTERNATIVE BATTERY Battery or more precisely‚ a cell – is a device in which the reaction between two substances can be made to occur in such a way that some of the chemical energy is converted to useful electricity. Since its invention‚ the battery has become the most common power source for many household and industrial applications. There are many ways to construct a battery‚ as well as ways to control its generated output. This Home-made Vinegar Battery is a battery

acid in a sample of vinegar? Prediction: The manufacture of claims on the label that the vinegar contains 5.0% acetic acid‚ which translates into a 0.87 mol/L concentration of acetic acid. The concentration of acetic acid in the vinegar sample should be the same. Purpose: If we add acid solution to basic solution to produce water and salt this activity is called titration. It involves carefully adding one solution to another until chemically equivalent amounts react. Vinegar is a solution of a
