DDWFTTW Science Fair Project: Cart Minus Propeller
This is a demonstration of our cart on the treadmill without the propeller. This video serves to show the difference between the cart’s movement with and without the propeller. In all instances, the cart is pushed backward due to frictional losses (which are normally overcome by the force of the propeller). … Direct Downwind Faster Than The Wind Science Fair Experiment Project DDFTTW
Abigale the Bichon Frise and the Science fair experiment
Which cookie will Abigale prefer? This is Abigale the Bichon Frise. She is helping Maddie with her kindergarten school Science Fair Project for 2009. Maddie took 3 types of dog treats - pupperoni, Beggin strips and Snausages (which are her favs) and put them out 3 seperate times in different sizes. 2 out of 3 times Abigale went for the Snausage. Her conclusion was Abigale is cute. (yes we knew that part) and that she went more for smell than size shape or color of the treats. Abigale enjoyed …

Make Silver Nitrate From Silver and Nitric Acid
gas too fast then you can pull the silver out of the acid to stop the reaction. Only aluminum is resistant to nitric acid, other metals are destroyed and will contaminate your acid. We’re going to use the silver nitrate to perform silver chloride photography, making mirrors, and even making flash powder. So please subscribe, rate and comment! … make Silver nitrate nitric acid aluminum nitrogen dioxide monoxide chemistry home science fair experiment project inorganic reaction nerd nurd rage …
