My First post so be nice, A set of simple intresting experiments that can be done at home with no fuss! I love science videos, so people of this science forum start making some videos of intresting experiments you find! Stars Happy New Year! My channel Link http://uk.youtube.com/geekstars Experiment 1: Bouncing Rice Win £5 with this methoud of making rice bounce!GeekStars for NewScientist Experiment 2: This experiment show that Co2 is actually heavier then air! The candle is put out with the falling Co2!AMAZING! Try it your self if you don't belive me! GeekStars for NewScientist Experiment 3: f = v/λ Upon initial stirring, entrained gas bubbles reduce the speed of sound in the liquid, lowering the frequency. As the bubbles clear, sound travels faster in the liquid and the frequency increases. This frequency f is equal to the speed v of the wave divided by the wavelength λ (lambda) of the wave GeekStars for NewScientist Experiment 4: Surface Tension Surface tension is an effect within the surface layer of a liquid that causes that layer to behave as an elastic sheet. Here the milk and food colourings are the surface and when the liquid soap hits it breaks the surface and the tenstion pulls back the food colouring! GeekStars for NewScientist Experiment 5: Green Eggs and Cabbage This experiment is taken from the new book from NewScientist by Mick O'Hare How to Fosseilise your hamster Make Eggs Turn Green with nother other then red cabbage juice! GeekStars for NewScientist Experiment 6: Ketchup Submarine This experiment shows that liquid is harder to compress than air! This experiment is taken from the new book from NewScientist by Mick O'Hare How to Fosseilise your hamster GeekStars for NewScientist Experiment 7: My Pound Coin Here you will see the effect of heating air and how it contracts when it cools! This experiment is adapted from the new book from NewScientist by Mick O'Hare How to Fosseilise your hamster GeekStars for NewScientist Enjoy
