Do You Know What Nano Means?
Published on Jan 31, 2013 This video won the 2011 Webby Award for Animation in the Online Film & Video Category. Produced by: Science Alberta Foundation Artist: Daniel Gies http://danielgies.carbonmade.com/ Nano may mean small, very small, but when it comes to making your body work it is big, very big. If your fingernail is about one millimeter thick, and a nanometer is one millionth of a millimeter, you can imagine that there are a lot of nanomaterials making up that small space. |

Liquid stacking in layers works because each liquid has a different density (children can use four different concentrations of salt water and food colouring to achieve the same results)
You'll need: Empty bottle measuring cup dark corn syrup dish washing liquid water (add food coloring) vegetable oil rubbing alcohol (add food coloring) Fill your bottle with water then pour it into a measuring cup, keeping track of how many total oz the bottle held. Then divide the number of liquids you want to stack, into the total amount of oz. That will tell you how many oz of each liquid you should pour into the bottle so that the layers are equal in size. Obviously if you want to have different sized layers, you can. When you add the corn syrup and dish washing liquid be sure to let the liquid drop straight into the container so that it doesnt touch the sides. When you add the water, vegetable oil and alcohol, tilt the bottle and let the liquid run slowly down the sides. If you pour it in too fast, it will mix with the other liquids.
