http://samlanblog.blogspot.com/2011/12/bending-water-with-static.html
Welcome to my blog. Follow Me，just click the bear below! Thursday, 1 December 2011. Bending Water with Static. A plastic comb (or an inflated balloon). A narrow stream of water from a tap.

Run the comb through your hair just as you normally would when brushing it (do this around 10 times). If you are using a balloon then rub it back and forth against your hair for a few seconds.

Welcome to my blog. Follow Me，just click the bear below! Tuesday, 15 November 2011. Rapid Color Changing Chemistry! Sometimes it’s hard to tell SCIENCE. And this little demonstration is a great example of that. In this experiment you will watch an almost clear liquid suddenly turn dark blue in a flash.

Welcome to my blog. Follow Me，just click the bear below! Saturday, 3 December 2011. Make Your Own Rainbow. A glass of water (about three quarters full).
