Believe it or not, that's what whipped cream looks like when viewed through a spectrometer. You can do this w...
Bottled-beer chuggers the world over already know that letting air into your beverage with a straw makes it pour faster into your mouth. Did you know, however, that the same technique can be modified and used to empty a fluid into another container (or onto the floor) even more quickly? This video will show you how to use a modified straw technique to introduce air into a large bottle of water or other drink bottle, causing the contents to empty at a torrid pace.
Want to test whether the soil sample or a water sample contains boron, watch this video. As shown in the video, the first step is to create test specimens of various concentrations using a simple turmeric and ethanol solution as a base for comparison. The basis of this experiment is the fact that curumin present in turmeric reacts with boron to form a reddish compound and so the result of this reaction can easily be verified visually.
